`#pragma mc_func` is an IBM XL feature that should be replaced by inline assembly. This PR adds an option `-ferr-pragma-mc-func-aix` to detect uses of `#pragma mc_func` and reports an error if the option is in effect. If `-fno-err-pragma-mc-func-aix` is in effect, `#pragma mc_func` is ignored even if `-Werror=unknown-pragmas` is in effect.
