632545e8ce [clang-tidy] Fix linking tests to LLVMTestingSupport
LLVMTestingSupport is not part of libLLVM, and therefore can not
be linked to via LLVM_LINK_COMPONENTS.  Instead, it needs to be
specified explicitly to ensure that it is linked explicitly
even if LLVM_LINK_LLVM_DYLIB is used.  This is consistent with handling
in clangd.

Fixes PR#48931

543cd89d3f [flang] Fix problems with constant arrays with lower bounds that are not 1
There were two problems with constant arrays whose lower bound is not 1.
First, when folding the arrays, we were creating the folded array to have lower
bounds of 1 but, we were not re-adjusting their lower bounds to the
declared values.  Second, we were not calculating the extents correctly.
Both of these problems led to bogus error messages.

I fixed the first problem by adjusting the lower bounds in
NonPointerInitializationExpr() in Evaluate/check-expression.cpp.  I wrote the
class ArrayConstantBoundChanger, which is similar to the existing class
ScalarConstantExpander.  In the process of implementing and testing it, I found
a bug that I fixed in ScalarConstantExpander which caused it to infinitely
recurse on parenthesized expressions.  I also removed the unrelated class
ScalarExpansionVisitor, which was not used.

I fixed the second problem by changing the formula that calculates upper bounds
in in the function ComputeUpperBound() in Evaluate/shape.cpp.

I added tests that trigger the bogus error messages mentioned above along with
a constant folding tests that uses array operands with shapes that conform but
have different bounds.

In the process of adding tests, I discovered that tests in
Evaluate/folding09.f90 and folding16.f90 were written incorrectly, and I
fixed them.  This also revealed a bug in contant folding of the
intrinsic "lbounds" which I plan to fix in a later change.

82847436e9 clang-cl: Invent a /winsysroot concept
On non-Windows platforms, --sysroot can be used to make the compiler use
a single, hermetic directory for all header and library files.

This is useful, but difficult to do on Windows. After D95472 it's
possible to achieve this with two flags:

    out/gn/bin/clang-cl win.c -fuse-ld=lld \
        /vctoolsdir path/to/VC/Tools/MSVC/14.26.28801 \
        /winsdkdir path/to/win_sdk

But that's still cumbersome: It requires two flags instead of one, and
it requires writing down the (changing) VC/Tools/MSVC version.

This adds a new `/winsysroot <dir>` flag that's effectively an alias to
these two flags. With this, building against a hermetic Windows
toolchain only needs:

    out/gn/bin/clang-cl win.c -fuse-ld=lld /winsysroot path

`/winsysroot <dir>` is the same as adding

    /vctoolsdir <dir>/VC/Tools/MSVC/<vctoolsver>
    /winsdkdir <dir>/Windows Kits/<winsdkmajorversion>

`<vctoolsver>` is taken from `/vctoolsversion` if passed, or else it's
the name of the directory in `<dir>/VC/Tools/MSVC` that's the highest
numeric tuple.

`<winsdkmajorversion>` is the major version in /winsdkversion if passed,
else it's the name of the directory in `<dir>/Windows Kits` that's the
highest number.

So `/winsysroot <path>` requires this subfolder structure:

  path/
    VC/
      Tools/
        MSVC/
          14.26.28801  (or another number)
            include/
            ...
    Windows Kits/
      10/
        Include/
          10.0.19041.0/ (or another number)
            um/
            ...
        Lib/
          10.0.19041.0/ (or another number)
            um/
              x64/

d0817b5f18 [clangd] Extract symbol-scope logic out of Quality, add tests. NFC
This prepares for reuse from the semantic highlighting code.

There's a bit of yak-shaving here:
 - when the enum is moved into the clangd namespace, promote it to a
   scoped enum. This means teaching the decision forest infrastructure
   to deal with scoped enums.
 - AccessibleScope isn't quite the right name: e.g. public class members
   are treated as accessible, but still have class scope. So rename to
   SymbolScope.
 - Rename some QualitySignals members to avoid name conflicts.
   (the string) SymbolScope -> Scope
   (the enum) Scope -> ScopeKind

f3a710cade [LTO] Update splitCodeGen to take a reference to the module. (NFC)
splitCodeGen does not need to take ownership of the module, as it
currently clones the original module for each split operation.

There is an ~4 year old fixme to change that, but until this is
addressed, the function can just take a reference to the module.

This makes the transition of LTOCodeGenerator to use LTOBackend a bit
easier, because under some circumstances, LTOCodeGenerator needs to
write the original module back after codegen.

2ff8662b5d [libcxx] Implement the stat function family on top of native windows APIs
While the windows CRTs (the modern UCRT, and the legacy msvcrt.dll
that mingw still often defaults to) do provide stat functions, they're
a bit lacking - they only provide second precision on the modification
time, lack support for symlinks and a few other details.

Instead reimplement them using a couple windows native functions,
getting exactly the info we need. (Technically, the implementation
within the CRT calls these functions anyway.)

If we only need a few fields, we could also do with fewer calls, as a
later optimization.
