Summary:
This change is preparation for a change that will allow targets to verify that the instructions
they emit meet the predicates they specify. This is useful to ensure that C++
legalization/lowering/instruction-selection doesn't incorrectly select code for a different
subtarget than intended. Such cases are not caught by the integrated assembler when emitting
instructions directly to an object file.

This results in a speed-up of over 6x on sqlite3.
Before:
$ time -p /org/llvm/utils/opt-viewer/opt-viewer.py ./MultiSource/Applications/sqlite3/CMakeFiles/sqlite3.dir/sqlite3.c.opt.yaml html
real 415.07
user 410.00

After with libYAML:

When a function is inlined, each instance is optimized in their own
inlining context. This can produce different remarks all pointing to
the same source line.
This adds a new column on the source view to display the inlining
context.

A relocatable immediate is either an immediate operand or an operand that
can be relocated by the linker to an immediate, such as a regular symbol
in non-PIC code.
Start using relocImm for 32-bit and 64-bit MOV instructions, and for operands
of type "imm32_su". Remove a number of now-redundant patterns.

With this we get a new field in the YAML record if the value being
streamed out has a debug location. For examples, please see the changes
to the tests.
This is then used in opt-viewer to display a link for the callee

Add a new script in llvm/utils/git-svn/. When present in the $PATH,
it enables a `git llvm` command. It is providing at this
point only the ability to push from the git monorepo: `git llvm push`.
It is intended to evolves with more features, for instance I plan on
features like `git llvm show r284955` to help working with sequential
revision numbers.
The push feature is taken from Justin Lebar's script available here:

Summary:
Some changes are made to cmake, especially the addition of a new

the monorepo directory structure.

point only the ability to push from the git monorepo: `git llvm push`.

A large number of tests in the LLVM tree use the default (CHECK) prefix
to indicate checked expressions via FileCheck. Highlight it as a
special comment. Although this wont get all the instances of the
checked patters, it is strictly better than the current state.

2 new intrinsics covering AVX-512 compress/expand functionality.

As it stands, the OperandMatchResultTy is only included in the generated
header if there is custom operand parsing. However, almost all backends
make use of MatchOperand_Success and friends from OperandMatchResultTy for
e.g. parseRegister. This is a pain when starting an AsmParser for a new
backend that doesn't yet have custom operand parsing. Move the enum to
MCTargetAsmParser.h.
This patch is a prerequisite for D23563

The CodeGenSchedModels::checkCompleteness routine in TableGen/
CodeGenSchedule.cpp is supposed to verify for each processor
model that is marked as "complete" that it actually defines a
scheduling class for each instruction.
However, this did not work correctly due to an incorrect
check whether a scheduling class has an itinerary.

In --unified-report mode, a single coverage report is prepared for all
specified binaries and written to *report_dir*. This mode is compatible
with all existing script options, including the --restrict mode which is
used to limit coverage reporting to certain files or directories.
This should not break any existing users of the script.

In --only-merge mode, the script terminates after the profile merging
step. This makes the script less stateful: it's more natural to split
the merge out into a separate step instead of relying on the first
invocation of the script to do it.
This should not break any existing users of the script.

Summary:
SetVector already used DenseSet, but SmallSetVector used std::set. This
leads to surprising performance differences. Moreover, it means that
the set of key types accepted by SetVector and SmallSetVector are
quite different!
In order to make this change, we had to convert some callsites that used
SmallSetVector<std::string, N> to use SmallSetVector<CachedHashString, N>
instead.

-debug-only=subtarget-emitter prints a lot of machine model diagnostics.
This prunes the output so that the "No machine model for XXX on processor YYY"
only appears when there is definitely no machine model for that opcode.
Previously it was printing that error even if the opcode was covered by
a more general scheduling class.

Summary:
The Python file `utils/lit/lit/ShUtil.py` contains:
1. Logic used by lit itself
2. A set of unit tests for that logic, which can be run by invoking
`python utils/lit/lit/ShUtil.py`
Move these unit tests to a `tests/unit` subdirectory of lit, and run
the tests as part of lit's test suite. This ensures that, should the
lit test suite be included in LLVM's own regression test suite, these
unit tests will also be run.
(Instructions on how to run lit's test suite can be found in
`utils/lit/README.txt`.)
