      - APX EGPRs are caller-saved registers and must be saved/restored across runtime calls to slow-path barriers.
      - ZRuntimeCallSpill is agnostic to live register, which makes it tricky to use any existing caller save register as a scratch register for bookkeeping an unaligned stack pointer.
