Running check-clang-tools on Windows produces 5 test failures:
Failed Tests (5):
Clang Tools :: clang-apply-replacements/ClangRenameClassReplacements.cpp
Clang Tools :: clang-apply-replacements/basic.cpp
Clang Tools :: clang-apply-replacements/format.cpp
Clang Tools :: clang-move/move-used-helper-decls.cpp
Clang Tools :: clang-tidy/infrastructure/export-diagnostics.cpp
Four of these failures are simply due to fixed character position
offsets differing on Windows versus Linux, since Windows line endings
take up two characters instead of one:
clang-apply-replacements/ClangRenameClassReplacements.cpp runs clang-rename -offset=254
clang-apply-replacements/Inputs/basic/file[12].yaml specify e.g. FileOffset: 148 and Offset: 298
clang-apply-replacements/Inputs/format/{no,yes}.yaml specify e.g. FileOffset: 94 and Offset: 94
clang-tidy/infrastructure/export-diagnostics.cpp specifies e.g. CHECK-YAML-NEXT: FileOffset: 30
(The move-used-helper-decls.cpp failure seems more complex; clang-move
adds a blank line after void HelperFun1() {} when
clang-move/Inputs/helper_decls_test.cpp has LF line endings, but does
not add a blank line when the input files has CRLF line endings. That
difference in behavior seems like it may be an actual bug, but I have
yet to track it down.)

With bc013b3e4e862da8d0c2d91cf99dcbebf124e4ac a new section called accessible functions was added to swift/include/swift/ABI/ObjectFile.h so this change adds support for dumping it out into the dSYM bundle

Follow-up to 458ead66dc, which replaced the bespoke CMakeLists.txt
file for building a custom instrumented libc++ with an invocation of the
runtimes build.
In the the bespoke CMakeLists.txt, the LIBCXX_CXX_ABI setting was forced
to libcxxabi, but this was not done for the CMake invocation for the
runtimes build. This would cause CMake configuration issues on platforms
where the default LIBCXX_CXX_ABI setting is not libcxxabi, such as
FreeBSD.
Add `-DLIBCXX_CXX_ABI=libcxxabi` to that invocation, to make sure the
custom instrumented libc++ always uses the expected ABI.

An infinite loop without any effects is illegal C++ and can be optimized

This reverts commit 2722ac65. As explained in D115906, this was actually
unnecessary and it broke the external threading configuration.

This works around a known issue in ASan. ASan doesn't instrument weak
symbols. Because instrumentation increases object size, the binary can
end up with two versions of the same object, one instrumented and one
not instrumented, with different sizes, which ASan will report as an ODR
violation. In libc++, this affects typeinfo for `std::bad_function_call`
which is emitted as a weak symbol in the test executable and as a strong
symbol in the shared library.
The main open issue for ASan appears to be

This mechanism was used for a couple of purposes, but the primary one was keeping track of which predicates in a union might apply to an expression. As these sets are small and agressively deduped, this has little value.

Upstream type test. Upstream test. Fix tests.
Do not run on windows, as that is not an implemented target.

Even if the search is marked as terminated after only looking at
the first operand, we'd still look at the remaining operands
before actually ending the search.
This seems pointless and wasteful, let's not do that.
Since we don't greedily flatten `umin_seq(a, umin(b, c))` into `umin_seq(a, b, c)`,
just looking at the operands of the outer-level `umin` is not sufficient,
and we need to recurse into all same-typed `umin`'s.
Pulled out of D106237, this replaces the X86ISD::AVG DAG node with the
generic ISD::AVGCEILU. It doesn't remove the detectAVGPattern method,
but the extra generic ISel matching does alter the existing test.

Section 10.2.2.4, paragraph 3 states that a procedure pointer with an explicit
interface must have the same characteristics as its target. Previously, we
interpreted this as disallowing such pointers to point to procedures with
implicit interfaces. But several other compilers allow this.
We make an exception for the case where the explicit interface cannot be
called via an implicit interface.
This change makes us allow this, also

Makes lld-link work in a non-MSVC shell by autodetecting MSVC toolchain. Also
adds support for /winsysroot and a few other switches.
All this is done by refactoring to share code with clang-cl's existing support
for the same.

this is the first step in unifying some of the logic between hwasan and
mte stack tagging. this only moves around code, changes to converge
different implementations of the same logic follow later.
