in section 10.1, __arm_{w,r}sr{,p,64}.
This includes arm_acle.h definitions with builtins and codegen to support
these, the intrinsics are implemented by generating read/write_register calls
which get appropriately lowered in the backend based on the register string
provided. SemaChecking is also implemented to fault invalid parameters.

Summary:
ACLE 2.0 section 9.2 defines the following "miscellaneous data processing intrinsics": `__clz`, `__cls`, `__ror`, `__rev`, `__rev16`, `__revsh` and `__rbit`.
`__clz` has already been implemented in the arm_acle.h header file. The rest are not supported yet. This patch completes ACLE data processing intrinsics.

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.

Although the functions are marked as always_inline, the compiler with which they
are used may not honour the extended attributes and emit them as functions. In
such a case, indicate that they should have extern "C" linkage and should not be
mangled in C++ style if used within C++.

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.
