During rule optimization, identical SameOperandMatchers are hoisted into a common group,
however previously only one operand index was considered.
Commutable patterns can introduce SameOperandMatcher checks where the second index is commuted,
resulting in a different check that cannot be hoisted.

lld/mac should be stable enough to use it as host linker. I've been
using `use_lld=true` in my local args.gn for many months now and it
works fine (and links much faster than ld64).

It seems to build fine (even though some tests fail), so might
as well let the bots build it. If it turns out to break a lot,
we can always turn it back off.

That way, the headers in llvm/utils/gn/secondary/compiler-rt/include
are copied when running `ninja compiler-rt`. (Previously, they were
only copied when running `check-hwasan` or when building the
compiler-rt/include target.)
(Since they should be copied only once, depend on the target in the
host toolchain. I think default_toolchain should work just as well,
it just needs to be a single fixed toolchain. check-hwasan depends
through host_toolchain, so let's use that here too.)
Prevents errors like
testing/fuzzed_data_provider.h:8:10: fatal error: 'fuzzer/FuzzedDataProvider.h' file not found
when building with locally-built clang. (For now, you still have to
explicitly build the 'compiler-rt' target. Maybe we should make the
clang target depend on that in the GN build?)

We would like to move ThinLTO’s battle-tested file caching mechanism to
the LLVM Support library so that we can use it elsewhere in LLVM.

This patch is to order the AVX instructions ahead of AVX512 instructions
in the matching table so that the AVX instructions can be matched first.
Thanks Craig and Shengchen for the idea.

We are seeing extremely long time in building AMDGPUInstPrinter.cpp
when profile instrumentation is enabled: It takes more than 5 minutes
(compared to ~8 seconds in non-instrument build).
This caused by the huge statements in printInstruction functions. In
profile instrumentation build, we need have extra control flow to
differentiate each case statement. This in turn adds significant
compile time in block placement and branch folding.
Function printInstruction is not likely to benefit from PGO build
as it's rarely executed in a typical compilation. So here I disable
the profile instrumentation for this function.

The operand of the second any_of in EnforceSmallerThan should be
B not S like the FP code in the if below.
Unfortunately, fixing that causes an infinite loop in the build
of RISCV. So I've added a workaround for that as well.
Fixes PR44768.

This moves the registry higher in the LLVM library dependency stack.
Every client of the target registry needs to link against MC anyway to
actually use the target, so we might as well move this out of Support.
This allows us to ensure that Support doesn't have includes from MC/*.
