David Green d96161a179 [ARM/AArch64] Move REQUIRES after update_cc_test_checks line. NFC
c17d9b4b12 added REQUIRES lines to a lot of Arm and AArch64
test, but added them to the very beginning, before the existing
update_cc_test_checks lines. This just moves them later so as to not
mess up the existing ordering when the checks are regenerated.

Saleem Abdulrasool c17d9b4b12 headers: optionalise some generated resource headers
This splits out the generated headers and conditonalises them upon the
target being enabled.

The motivation here is that the RISCV header alone added 10MB to the
resource directory, which was previously at 10MB, increasing the build
size and time. This header is contributing ~50% of the size of the
resource headers (~10MB).

The ARM generated headers are contributing about ~10% or 1MB.

This could be extended further adding only the static resource headers
for the targets that the LLVM build supports.

The changes to the tests for ARM mirror what the RISCV target already
did and rnk identified as a possible issue.

Testing:
  cmake -G Ninja -D LLVM_TARGETS_TO_BUILD=X86 -D LLVM_ENABLE_PROJECTS="clang;lld" ../clang
  ninja check-clang

Chandler Carruth 16e6bc23a1 [x86] Teach the builtin argument range check to allow invalid ranges in
dead code.

This is important for C++ templates that essentially compute the valid
input in a way that is constant and will cause all the invalid cases to
be dead code that is deleted. Code in the wild actually does this and
GCC also accepts these kinds of patterns so it is important to support
it.

To make this work, we provide a non-error path to diagnose these issues,
and use a default-error warning instead. This keeps the relatively
strict handling but prevents nastiness like SFINAE on these errors. It
also allows us to safely use the system to diagnose this only when it
occurs at runtime (in emitted code).

Entertainingly, this required fixing the syntax in various other ways
for the x86 test because we never bothered to diagnose that the returns
were invalid.

Since debugging these compile failures was super confusing, I've also
improved the diagnostic to actually say what the value was. Most of the
checks I've made ignore this to simplify maintenance, but I've checked
it in a few places to make sure the diagnsotic is working.

Depends on D48462. Without that, we might actually crash some part of
the compiler after bypassing the error here.

Thanks to Richard, Ben Kramer, and especially Craig Topper for all the
help here.

Luke Geeson dc54b37414 [AArch64] Corrected FP16 Intrinsic range checks in Clang + added Sema tests
Summary:
This fixes the ranges for the vcvth family of FP16 intrinsics in the clang front end. Previously it was accepting incorrect ranges
-Changed builtin range checking in SemaChecking
-added tests SemaCheck changes - included in  their own file since no similar one exists
-modified existing tests to reflect new ranges
