The builtin __rlwnm is currently constrained to accept only constants
for the shift parameter but the instructions emitted for it have no such
constraint, this patch allows the builtins to accept variable shift.

The builtins: `__compare_and_swaplp`, `__fetch_and_addlp`,
` __fetch_and_andlp`, `__fetch_and_orlp`, `__fetch_and_swaplp` are
64 bit only. This patch ensures the compiler produces an error in 32 bit mode.

Since XLC only ever shipped on PowerPC AIX and Linux, it is not reasonable to
provide the compatibility macros on any target other than those two. This patch
restricts those macros to AIX/Linux.

The __darn family of builtins are only available on Pwr9,
and only __darn_32 is available on both 64 and 32 bit, while the rest
are only available on 64 bit. The patch adds sema checking
for these builtins and separate the __darn_32's 32 bit
test cases.

To match xlc behaviour and definition in the PowerPC ISA3.1,
it is a better idea to have ibm-clang produce an error when a
0 is passed to the builtin, which will match xlc's behaviour.
This patch changes the accepted range from 0 to 31 to 1 to 31.

Implemented builtins for mtmsr, mfspr, mtspr on PowerPC;
the patch is intended for XL Compatibility.
Differential revision: https://reviews.llvm.org/D106130
Added a number of different builtins that exist in the XL compiler. Most of
these builtins already exist in clang under a different name.

This patch is in a series of patches to provide builtins for compatibility
with the XL compiler. This patch adds the builtins and emit target independent
code for rotate related operations.

This patch implements trap and FP to and from double conversions. The builtins
generate code that mirror what is generated from the XL compiler. Intrinsics
are named conventionally with builtin_ppc, but are aliased to provide the same
builtin names as the XL compiler.

This patch implaments the load and reserve and store conditional
builtins for the PowerPC target, in order to have feature parody with
xlC on AIX.
