This prevents us from creating temporary PoisoningVHs and
AssertingVHs while performing hashmap lookups. As such, it only
matters in assertion-enabled builds.
In C++17 the operand(s) of an overloaded operator are sequenced as for
the corresponding built-in operator when the overloaded operator is
called with the operator notation ([over.match.oper]p2).

This potentially related to https://bugs.llvm.org/show_bug.cgi?id=46335
and causes a slight compile-time regression. Revert while investigating.
This reverts commit d99a1848c4f8ca164c0c0768e10eafc850b2a68a.
When building runtimes, the compiler name (e.g. clang, clang-cl) is set based on
`CMAKE_SYSTEM_NAME` passed to `llvm_ExternalProject_Add()` through `CMAKE_ARGS` argument.
This mechanism doesn't work well if the target is Windows host.
`runtime_default_target()`/`builtin_default_target()` doesn't provide a way
to specify `CMAKE_SYSTEM_NAME` and doesn't set it either.
This patch appends variables specified in `RUNTIMES_CMAKE_ARGS`/`BUILTINS_CMAKE_ARGS`
to `CMAKE_ARGS` argument of `llvm_ExternalProject_Add()` in the case of called
from `runtime_default_target()`/`builtin_default_target()` thus in particular
it allows passing CMAKE_SYSTEM_NAME whenever it is required.

We were missing the modrm byte this instruction has according
to current Intel SDM. Experiments with gcc indicate that different
modrm values are chosen based on 2 operands so I've added those
as well.
I think our previous implementation was based on an older behavior of
binutils that has since been changed.
Avoid using max on unsigned constants, in case the caller is using 0 we
end up with:
warning: taking the max of unsigned zero and a value is always equal to the other value [-Wmax-unsigned-zero]
Instead we can just use native TableGen to fold the comparison here.
These are documented as using modrm byte of 0xe8, 0xf0, and 0xf8
respectively. But hardware ignore bits 2:0. So 0xe9-0xef is treated
the same as 0xe8. Similar for the other two.
Fixing this required adding 8 new formats to the X86 instructions
to convey this information. Could have gotten away with 3, but
adding all 8 made for a more logical conversion from format to
modrm encoding.
I renumbered the format encodings to keep the register modrm
formats grouped together.
Keep deprecated -fsanitize-coverage-{white,black}list as aliases for compatibility for now.

When an invoke instruction is converted to a call its
profile metadata is dropped because it has incompatible
format (see commit 16ad6eeb94ff).
This patch adds an attempt to convert profile data to
format of the call instruction. This used to work well
before the commit dcfa78a4ccec.

Clang is missing one of the conditions for C99 6.5.9p2, where comparison
between pointers must either both point to incomplete types or both
point to complete types. This patch adds an extra check to the clause
where two pointers are of compatible types.
This only applies to C89/C99; the relevant part of the standard was
rewritten for C11.

At this point in this code:
- COMPILER_RT_DEFAULT_TARGET_TRIPLE is "i686-linux-android"
- arch is "i386"
The get_compiler_rt_target function currently turns that into:
i686-android-linux-android
The ${COMPILER_RT_OS_SUFFIX} is "-android" and redundant, so stop
adding it.
The get_compiler_rt_target() function is used for the
LLVM_ENABLE_PER_TARGET_RUNTIME_DIR mode that isn't normally used with
Android.

This is a fix for PR #46392 (Diagnostic message (error) related to
ThinLTO caching needs to be downgraded to a remark).
There are diagnostic messages related to ThinLTO caching that contain
the word "error", but they are really just notices/remarks for users,
and they don't cause a build failure. The word "error" appearing can be
confusing to users, and may even cause deeper problems.
User's build system might be designed to interpret any error messages
(even a benign error message as the one above) reported by the compiler
as a build failure, thus causing the build to fail "needlessly". In
short, the term "error" in this diagnostic is misleading at best, and
may be causing build systems to fail at worst.

When created in RegStackify pass, `TEE` has two destinations, where
op0 is stackified and op1 is not. But it is possible that
op0 becomes unstackified in `fixUnwindMismatches` function in
CFGStackify pass when a nested try-catch-end is introduced, violating
the invariant of `TEE`s destinations.
In this case we convert the `TEE` into two `COPY`s, which will
eventually be resolved in ExplicitLocals.
