Michael Spencer 16af23fae8 [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.
