arm: Fix an rtl checking failure in cde-errors.c

Browse source 
cde-errors.c and cde-mve-error-2.c were failing with an rtl checking
failure because we applied UINTVAL to a nonconstant argument
(specifically a REG).

	* config/arm/arm-builtins.c (arm_expand_builtin_args): Only apply
	UINTVAL to CONST_INTs.
