aarch64: Add support for SME2 intrinsics
This patch adds support for the SME2 <arm_sme.h> intrinsics. The
convention I've used is to put stuff in aarch64-sve-builtins-sme.*
if it relates to ZA, ZT0, the streaming vector length, or other
such SME state. Things that operate purely on predicates and
vectors go in aarch64-sve-builtins-sve2.* instead. Some of these
will later be picked up for SVE2p1.
We previously used Uph internally as a constraint for 16-bit
immediates to atomic instructions. However, we need a user-facing
constraint for the upper predicate registers (already available as
PR_HI_REGS), and Uph makes a natural pair with the existing Upl.
