[PATCH] Update decls in genemit.c

[Marek Polacek]

Since r225883, genemit.c's gen_insn/gen_expand/gen_split have a parameter
of type md_rtx_info *, not rtx, but the function prototypes weren't updated,
which results into 'declared but never defined' warnings.  The following
trivial patch updates the declarations.

Bootstrapped/regtested on x86_64-linux, ok for trunk?
