  Log Message:
  -----------
  [LFI][AArch64] Add AArch64 LFI rewrites for system instructions (#186896)

This builds on the MCLFIRewriter infrastructure to add the
AArch64-specific LFI rewriter, which rewrites AArch64 instructions for
LFI sandboxing during the assembler step.

The initial rewriter handles system instructions: system calls, thread
pointer accesses, and also rejects modifications to reserved registers.
