This patch adds support for:

- Querying the PSTATE.SM state with @llvm.aarch64.sme.get.pstatesm
- Reading/writing the TPIDR2 register with new @llvm.aarch64.sme.get.tpidr2 and @llvm.aarch64.sme.set.tpidr2 intrinsics.

Tests added here:

  CodeGen/AArch64/sme-get-pstatesm.ll
  CodeGen/AArch64/sme-read-write-tpidr2.ll
