c745ae4836 AArch64 popt: don't replace registers with X/WZR 
Most arithmetic/logica instructions don't support X/WZR as operand (since
you should use movk with the calculated constant in that case)

Resolves #39372

3f19bd693f + Add new LastCommonAsmOp constant to arm and aarch64 CPU targets. 
* Uses this new constant to define TCommonAsmOps set type.
  + Use this constant in armgen/aoptarm MatchInstruction function,
    to avoid a range check error when compiling with -CriotR with optimization.

9376f5a43a * AArch64: added SIMD instructions (only plain ARMv8-A for now) 
o added AArch64 regset parsing support in assembler reader, means that "{"
     no longer starts comments there (like in the ARM assembler reader)
   o added AArch64 indexed SIMD register support and removed old cg hacks
     that worked around its absence
