gimple-ssa-sprintf.c: Fix comment formatting.

	* gimple-ssa-sprintf.c: Fix comment formatting.
	(format_integer): Use is_gimple_assign.
	(pass_sprintf_length::handle_gimple_call): Use gimple_call_builtin_p
	and gimple_call_fndecl.  Reorder case BUILT_IN_SPRINTF_CHK.  Fix up
	BUILT_IN_SNPRINTF_CHK comment.  Replace "to to" with "to" in comment.
	(pass_sprintf_length::execute): Use is_gimple_call.
