Warning fixes:

	* builtins.c (expand_builtin_memcmp, expand_builtin_strcmp): Wrap
	prototypes in macro HAVE_cmpstrsi.

	* cpplib.c (cpp_get_token): Remove unused label `op3'.

	* emit-rtl.c (operand_subword): Remove unused variable
	`bits_per_word'.

	* rtl.c (shallow_copy_rtx): Remove unused variable `format_ptr'.

	* tree.c (chainon): Wrap variable `t2' in macro ENABLE_CHECKING.
