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.
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

Summary:
Change the vsqadd scalar instrinsics to have the second argument as signed values, not unsigned,
accordingly to https://developer.arm.com/architectures/instruction-sets/simd-isas/neon/intrinsics
The existing unsigned argument can cause faulty code as negative float to unsigned conversion is
undefined, which llvm/clang optimizes away.
