objtool: Add asm version of STACK_FRAME_NON_STANDARD
commit 081df94301e317e84c3413686043987da2c3e39d upstream.
To be used for adding asm functions to the ignore list. The "aw" is
needed to help the ELF section metadata match GCC-created sections.
Otherwise the linker creates duplicate sections instead of combining
them.
