This patch moves the creation of the '-Wspir-compat' argument from cc1 to the driver.
Without this change, generating command line arguments from `CompilerInvocation` cannot be done reliably: there's no way to distinguish whether '-Wspir-compat' was passed to cc1 on the command line (should be generated), or if it was created within `CompilerInvocation::CreateFromArgs` (should not be generated).
This is also in line with how other '-W' flags are handled.
(This was introduced in D21567.)

This patch stops creating the '-Wno-stdlibcxx-not-found' argument in `CompilerInvocation::CreateFromArgs`.
The code was added in 2e7ab55e657f (a follow-up to D48297). However, D61963 removes relevant tests and starts explicitly passing '-Wno-stdlibcxx-not-found' to the driver. I think it's fair to assume this is a dead code.

Basic block sections enables function sections implicitly, this is not needed
and is inefficient with "=list" option.
We had basic block sections enable function sections implicitly in clang. This
is particularly inefficient with "=list" option as it places functions that do
not have any basic block sections in separate sections. This causes unnecessary
object file overhead for large applications.
This patch disables this implicit behavior. It only creates function sections
for those functions that require basic block sections.
This patch is the second of two patches and this patch removes the implicit
enabling of function sections with basic block sections in clang.

This patch generates the `-f[no-]finite-loops` arguments from `CompilerInvocation` (added in D96419), fixing test failures of Clang built with `-DCLANG_ROUND_TRIP_CC1_ARGS=ON`.

This patch adds 2 new options to control when Clang adds `mustprogress`:
1. -ffinite-loops: assume all loops are finite; mustprogress is added
to all loops, regardless of the selected language standard.
2. -fno-finite-loops: assume no loop is finite; mustprogress is not
added to any loop or function. We could add mustprogress to
functions without loops, but we would have to detect that in Clang,
which is probably not worth it.

Some Windows build bots report `FileSystemOpts` and `MigratorOpts` as undeclared. This fix renames the parameter and declares a local variable with the original name.
This patch splits out the last two option groups (`Filesystem` and `Migrator`) into their own `Parse`/`Generate` functions.
This effectively removes the need for `parseSimpleArgs` and marshalling block in `CompilerInvocation::generateCC1CommandLine`.
The two new `Parse`/`Generate` functions are not part of the round-trip, because they contain no custom code and the very next patch starts round-tripping the whole `CompilerInvocation`.

Regular expression patterns passed through the command line are being used to create an instances of `llvm::Regex` and thrown away.
There is no API to serialize `Regex` back to the original pattern. This means we have no way to reconstruct the original pattern from command line. This is necessary for serializing `CompilerInvocation`.
This patch stores the original pattern string in `CodeGenOptions` alongside the `llvm::Regex` instance.

This patch implements generation of remaining language options and tests it by performing parse-generate-parse round trip (on by default for assert builds, off otherwise).
This patch also correctly reports failures in `parseSanitizerKinds`, which is necessary for emitting diagnostics when an invalid sanitizer is passed to `-fsanitize=` during round-trip.
This patch also removes TableGen marshalling classes from two options:
* `fsanitize_blacklist` When parsing: it's first initialized via the generated code, but then also changed by manually written code, which is confusing.
* `fopenmp` When parsing: it's first initialized via generated code, but then conditionally changed by manually written code. This is also confusing. Moreover, we need to do some extra checks when generating it, which would be really cumbersome in TableGen. (Specifically, not emitting it when `-fopenmp-simd` was present.)

This patch added a distinct CUID for each input file, which is represented by InputAction.
clang initially creates an InputAction for each input file for the host compilation. In CUDA/HIP action
builder, each InputAction is given a CUID and cloned for each GPU arch, and the CUID is also cloned. In this way,
we guarantee the corresponding device and host compilation for the same file shared the
same CUID. On the other hand, different compilation units have different CUID.
-fuse-cuid=random|hash|none is added to control the method to generate CUID. The default
is hash. -cuid=X is also added to specify CUID explicitly, which overrides -fuse-cuid.

This reverts commit 6039f821 and reapplies bff6d9bb.
Clang's Index/implicit-attrs.m test invokes c-index-test with -fobjc-arc. This flag is not compatible with -fobjc-runtime=gcc, which gets implied on Linux.
The original commit uncovered this by correctly reporting issues when parsing -cc1 command line.
This commit fixes the test to explicitly provide ObjectiveC runtime compatible with ARC.
This patch correctly reports success/failure of `ParseLangArgs`. Besides being consistent with other `Parse` functions, this is required to make round-tripping of `LangOptions` work.

This patch implements generation of remaining header search arguments.
It's done manually in C++ as opposed to TableGen, because we need the flexibility and don't anticipate reuse.

This reverts commit 9ad94c12
It turns out that to correctly generate command line flags for LangOptions::OpenMP and LangOptions::OpenMPSimd, we need the flexibility of C++.
This patch makes all macros forwarding to `PARSE_OPTION_WITH_MARSHALLING` and `GENERATE_OPTION_WITH_MARSHALLING` variadic.
Sice we will be splitting up all CompilerInvocation parts, this will allow us to avoid a lot of boilerplate code.
The local macros prefix forwarded arguments with local variables required by the main macros. The `{THIS,NO}_PREFIX` macros make it possible for forwarding macros in member functions (`parseSimpleArgs`, `generateCC1CommandLine`) to prefix keypaths with `this->`. (Some build bots seem to require that.)

This patch moves parsing of header search options from `generateCC1Options` to separate `GenerateHeaderSearchArgs`.
The round-trip algorithm in D94472 requires this separation to be able to run parsing and generating **only** for the options that need to be tested via round-tripping.
This also moves the `GENERATE_OPTION_WITH_MARSHALLING` to the top of the file, because other kinds of options will be generated in separate functions that will be spread throughout `CompilerInvocation.cpp` to be close to their parsing counterparts.

There are two use cases.
Assembler
We have accrued some code gated on MCAsmInfo::useIntegratedAssembler(). Some
features are supported by latest GNU as, but we have to use
MCAsmInfo::useIntegratedAs() because the newer versions have not been widely
adopted (e.g. SHF_LINK_ORDER 'o' and 'unique' linkage in 2.35, --compress-debug-sections= in 2.26).
Linker
We want to use features supported only by LLD or very new GNU ld, or don't want
to work around older GNU ld. We currently can't represent that "we don't care
about old GNU ld". You can find such workarounds in a few other places, e.g.
Mips/MipsAsmprinter.cpp PowerPC/PPCTOCRegDeps.cpp X86/X86MCInstrLower.cpp
AArch64 TLS workaround for R_AARCH64_TLSLD_MOVW_DTPREL_* (PR ld/18276),
R_AARCH64_TLSLE_LDST8_TPREL_LO12 (https://bugs.llvm.org/show_bug.cgi?id=36727https://sourceware.org/bugzilla/show_bug.cgi?id=22969)
Mixed SHF_LINK_ORDER and non-SHF_LINK_ORDER components (supported by LLD in D84001;
GNU ld feature request https://sourceware.org/bugzilla/show_bug.cgi?id=16833 may take a while before available).
This feature allows to garbage collect some unused sections (e.g. fragmented .gcc_except_table).
This patch adds `-fbinutils-version=` to clang and `-binutils-version` to llc.
It changes one codegen place in SHF_MERGE to demonstrate its usage.
`-fbinutils-version=2.35` means the produced object file does not care about GNU
ld<2.35 compatibility. When `-fno-integrated-as` is specified, the produced
assembly can be consumed by GNU as>=2.35, but older versions may not work.
`-fbinutils-version=none` means that we can use all ELF features, regardless of
GNU as/ld support.
Both clang and llc need `parseBinutilsVersion`. Such command line parsing is
usually implemented in `llvm/lib/CodeGen/CommandFlags.cpp` (LLVMCodeGen),
however, ClangCodeGen does not depend on LLVMCodeGen. So I add
`parseBinutilsVersion` to `llvm/lib/Target/TargetMachine.cpp` (LLVMTarget).

The `LangStandard::Kind` parsed from command line arguments is used to set up some `LangOption` defaults, but isn't stored anywhere.

This patch moves the parsing of `{Lang,CodeGen}Options` from `parseSimpleArgs` to the original `Parse{Lang,CodeGen}Args` functions.
This ensures all marshalled `LangOptions` are being parsed **after** the call `setLangDefaults`, which in turn enables us to marshall `LangOptions` that somehow depend on the defaults. (In a future patch.)
Now, `CodeGenOptions` need to be parsed **after** `LangOptions`, because `-cl-mad-enable` (a `CodeGenOpt`) depends on the value of `-cl-fast-relaxed-math` and `-cl-unsafe-math-optimizations` (`LangOpts`).
Unfortunately, this removes the nice property that marshalled options get parsed in the exact order they appear in the `.td` file. Now we cannot be sure that a TableGen record referenced in `ImpliedByAnyOf` has already been parsed. This might cause an ordering issues (i.e. reading value of uninitialized variable). I plan to mitigate this by moving each `XxxOpt` group from `parseSimpleArgs` back to their original parsing function. With this setup, if an option from group `A` references option from group `B` in TableGen, the compiler will require us to make the `CompilerInvocation` member for `B` visible in the parsing function for `A`. That's where we notice that `B` didn't get parsed yet.
