  Opting out of Clang 16 ABI Changes for AIX and z/OS

There is already a GCC compatibility gap on AIX, & GCC compatibility is
not a concern on z/OS. GCC compatibility is not sufficient motivation
for breaking ABI on AIX and z/OS. This opts out of changes introduced in
https://reviews.llvm.org/D119051. For AIX only, also opt out of D117616
(which z/OS had picked up at the time ABI stabilization occurred).
