Add support for function inlining at OPT(0) [Metal C]

The METAL option of the xlc compiler does not support selectively inlining functions without optimizing the rest of the code

We would like to be able to use a compiler attribute (such as "__always_inline__" or "_inline") to force inlining of certain functions, regardless of the level of compiler optimization

    This RFE is being rejected because the strongest "__always_inline__" attribute is still only a hint to the compiler. The compiler still reserves the right for not to inline a function, under some circumstances. Also, this scenario would require a significant restructuring of the compiler backend architecture.

    Hi, we are still evaluating this RFE and require some more time.
