In some cases, it would be useful if the presence of the gcc -mregnames
option was not only communicated to the assembler, but also to the C
program being compiled. This comes up in an unusual usage of
inline-assembler operands, where the ambiguity between literals and
register names is a problem. (http://sourceware.org/PR11821).
With such a macro (say, -D__GCC_REGNAMES), the inline-asm code could
emit extra code strings to allow resolution of the ambiguities.
