  Log Message:
  -----------
  [AArch64][SME2/SVE2p1] Add predicate-as-counter intrinsics for ptrue/cntp

These intrinsics are used to implement:
* svptrue_c8(), svptrue_c16(), etc.
* svcntp_c8(svcount_t pnn, uint64_t vl), svcntp_c16(...), etc.

  Log Message:
  -----------
  [AArch64][SME2/SVE2p1] Add predicate-as-counter intrinsics for while*

These intrinsics are used to implement the while intrinsics that result
in a predicate-as-counter value, e.g.

  __attribute__((arm_streaming))
  svcount_t svwhilelt_c8(int64_t rn, int64_t rm, uint64_t vl)
