The CMAKE_BUILD_TYPE is only meaningful to single-configuration
generators (such as make and Ninja). For multi-configuration generators
like Xcode and MSVC this variable won't be set, resulting in a CMake
error.
The DAG behavior allows matchching input patterns with a single result
to the first result of an output instruction that defines multiple
results. The remaining defs are implicitly dead.
This starts to fix using manual selection for AMDGPU add/sub (although
it's still needed, mostly because it's also still needed for
G_PTR_ADD).
A comma is not required between a scale factor and a following

This seems obvious in hindsight, but the result is surprising.
I've measured compile-time of `-openmpopt` pass standalone
on RawSpeed unity build, and while there is some OpenMP stuff,
most is not OpenMP. But nonetheless the pass does a lot of costly
preparations before ever trying to look for OpenMP stuff in SCC.

This cleanup patch unifies all methods called GetByteSize() in the
ValueObject hierarchy to return an optional, like the methods in
CompilerType do. This means fewer magic 0 values, which could fix bugs
down the road in languages where types can have a size of zero, such
as Swift and C (but not C++).

2. Fix the type of the first argument of synchronize_ty in rth.h, device id is int32_t which is consistent with other functions.

Summary:
This commit is somewhat NFC-ish today as the environment of triples
is not considered when comparing s if one of them is
not set (I plan to change that).
We have made simulator triples unambiguous these days, but the
simulator platforms still advertise triples without the
environment. This wasn't an issue when the sims ran only on
a very different architecure than the real device, but this
has changed with Apple Silicon.
This patch simplifies the way GetSupportedArchitectureAtIndex
is implemented for the sim platforms and adds the environment.
It also trivially adds support for Apple Silicon to those
platforms.

The LowerAffine psas was a FunctionPass only for legacy

Summary: This patch disables implicit builtin knowledge about memcmp-like functions when compiling the program for fuzzing, i.e., when -fsanitize=fuzzer(-no-link) is given. This allows libFuzzer to always intercept memcmp-like functions as it effectively disables optimizing calls to such functions into different forms. This is done by adding a set of flags (-fno-builtin-memcmp and others) in the clang driver. Individual -fno-builtin-* flags previously used in several libFuzzer tests are now removed, as it is now done automatically in the clang driver.
The patch was once reverted in 8ef9e2bf355d05bc81d8b0fe1e5333eec59a0a91, as this patch was dependent on a reverted commit f78d9fceea736d431e9e3cbca291e3909e3aa46d. This reverted commit was recommitted in 831ae45e3dc609e43ba561af07670a8fe47461ef, so relanding this dependent patch too.

New change: check for existence of field `cycles` in perf_branch_entry before enabling this mode.
This should prevent compilation errors when building for older kernel whose headers don't support it.
This cleans up several CMakeLists.txt's where -Wno-suggest-override was manually specified. These test targets now inherit this flag from the gtest target.
Some unittests CMakeLists.txt's, in particular Flang and LLDB, are not touched by this patch. Flang manually adds the gtest sources itself in some configurations, rather than linking to LLVM's gtest target, so this fix would be insufficient to cover those cases. Similarly, LLDB has subdirectories that manually add the gtest headers to their include path without linking to the gtest target, so those subdirectories still need -Wno-suggest-override to be manually specified to compile without warnings.

Otherwise, if a Lit script contains escaped substitutions (like %%p in this test https://github.com/llvm/llvm-project/blob/master/compiler-rt/test/asan/TestCases/Darwin/asan-symbolize-partial-report-with-module-map.cpp#L10), they are unescaped during recursive application of substitutions, and the results are unexpected.
We solve it using the fact that double percent signs are first replaced with #_MARKER_#, and only after all the other substitutions have been applied, #_MARKER_# is replaced with a single percent sign. The only change is that instead of replacing #_MARKER_# at each recursion step, we replace it once after the last recursion step.
