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.

Summary:
The range checks performed for the vqrdmulh_lane and vqrdmulh_lane Neon
intrinsics were incorrectly using their return type as the base type for
the range check performed on their 'lane' argument.
This patch updates those intrisics to use the type of the proper reference
argument to perform the range checks.

Summary:
Range checks were not properly performed in the lane arguments of Neon
intrinsics implemented based on splat operations. Calls to those
intrinsics where translated to `__builtin__shufflevector` calls directly
by the pre-processor through the arm_neon.h macros, missing the chance
for the proper range checks.
This patch enables the range check by introducing an auxiliary splat
instruction in arm_neon.td, delaying the translation to shufflevector
calls to CGBuiltin.cpp in clang after the checks were performed.

Summary:
Some of the `*_laneq` intrinsics defined in arm_neon.td were missing the
setting of the `isLaneQ` attribute. This patch sets the attribute on the
related definitions, as they will be required to properly perform range
checks on their lane arguments.
