[ARM] Generate CMSE instructions from CMSE intrinsics
This patch adds instruction selection patterns for the TT, TTT, TTA, and TTAT
instructions and tests for llvm.arm.cmse.tt, llvm.arm.cmse.ttt,
llvm.arm.cmse.tta, and llvm.arm.cmse.ttat intrinsics (added in a previous
patch).
Patch by Javed Absar.
