gcc/genflags.c: Improve error message

When an iterator cannot be expanded, it is helpful to see the expanded
name which is causing problems.  It would be better to also print the
current iterator value (which couldn't match), but I couldn't find
how.

	* genflags.c (gen_insn): Print failed expansion string.
