Headers: add hint intrinsics to arm_acle.h This adds the ARM ACLE hint intrinsic wrappers to arm_acle.h. These need to be protected with a !defined(_MSC_VER) since MSVC (and thus clang in compatibility mode) provide these wrappers as proper builtin intrinsics. llvm-svn: 212891

[clang][Headers] Use __has_builtin instead of _MSC_VER. arm_acle.h relied on `_MSC_VER` to determine if a given function was already defined as a builtin. This was incorrect because `-fms-extensions` enables these builtins, but is not responsible for defining `_MSC_VER` on any target. The next closest thing is `_MSC_EXTENSIONS`, which is only defined on Windows targets, but even this is suboptimal. What this conditional is actually trying to determine is if the given functions are defined as builtins, so just check that directly. I also attempted to do this for `__nop`, but in that case intrin.h, which is only includable if `_MSC_VER` is defined, has its own definition. So in that case `_MSC_VER` is correct.

Introduce arm_acle.h supporting existing LLVM builtin intrinsics Summary: This patch introduces ACLE header file, implementing extensions that can be directly mapped to existing Clang intrinsics. It implements for both AArch32 and AArch64.
