Small warnings sweep

["Zack Weinberg" <zackw at stanford dot edu>]

This patch fixes a few warnings - unused variable, implicit
declaration.

Bootstrapped i386-linux; applied.

There are three unused variables in i386.c's ix86_init_builtins
(int_ftype_v4sf_int, di_ftype_di_int, v8qi_ftype_v8qi_di) but I don't
understand what's going on in there so I left it alone.

zw

	* builtins.c (expand_builtin_strlen): Remove unused mode
	argument.
	* gcc.c (process_command): Remove unused variable.
	* fold-const.c: Include expr.h.
	* recog.c: Include reload.h.
	* Makefile.in (recog.o, fold-const.o): Update deps.

cp:
	* decl.c: Include tm_p.h.
