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

This is a follow-up from https://reviews.llvm.org/D61717. Where Richard
described the issue with compiling arm_neon.h under
-flax-vector-conversions=none. It looks like the example reproducer does
actually work but what was missing was a test entry for that target.

This patch broke the Sanitizer buildbots. Please see the commit's
differential revision for more information
(https://reviews.llvm.org/D67678).
This reverts commit b72a8c65e4.
Just running -fsyntax-only over arm_neon.h doesn't cover some intrinsics
which are defined using macros. Add more test coverage for that.
arm-neon-header.c wasn't checking the full set of available NEON target
features; change the target architecture of the test to account for
that.
Fix the generator for arm_neon.h to generate casts in more cases where
they are necessary.
Fix VFMLAL_LOW etc. to express their signatures differently, so the
builtins have the expected type. Maybe the TableGen backend should
detect intrinsics that are defined the wrong way, and produce an error.
The rules here are sort of strange.

Really, we were already 99% of the way there; just needed a couple minor
fixes that affected 64-bit-only builtins. Based on D61717.
Note that the change to builtin_str changes the type of a few
__builtin_neon_* intrinsics that had the "wrong" type.

If clang is configured to use libcxx as the default C++ standard
library, then using "none" for the OS in the target triple will cause
libcxx to #error needlessly. Passing -nostdinc++ is a workaround for
these tests. See also: https://reviews.llvm.org/D68075
Please note: this workaround will probably exist for a few years until
the installed version of libcxx is updated.

levels:
-- none: no lax vector conversions [new GCC default]
-- integer: only conversions between integer vectors [old GCC default]
-- all: all conversions between same-size vectors [Clang default]
For now, Clang still defaults to "all" mode, but per my proposal on
cfe-dev (2019-04-10) the default will be changed to "integer" as soon as
that doesn't break lots of testcases. (Eventually I'd like to change the
default to "none" to match GCC and general sanity.)
Following GCC's behavior, the driver flag -flax-vector-conversions is
translated to -flax-vector-conversions=integer.
This reinstates r371805, reverted in r371813, with an additional fix for
lldb.

Summary:
The inline attribute is not valid for C standard 89. Replace the argument in the generation of header files with __inline, as well adding tests for both header files.

This does not work so well with the -fno-lax-vector-conversions option for
testing the arm_neon.h header but that is a really useful test, so I split
this out to a separate Sema test to check for the warning.
