  Log Message:
  -----------
  [llvm][CodeGen] IR intrinsics for SVE2 contiguous conflict detection instructions.

Summary:
The IR intrinsics are mapped to the following SVE2 instructions:

* WHILERW <Pd>.<T>, <Xn>, <Xm>
* WHILEWR <Pd>.<T>, <Xn>, <Xm>

The intrinsics introduced in this patch are the IR counterpart of the
SVE ACLE functions `svwhilerw` and `svwhilewr` (all data type
variants).
