Don't ICE on vectors of enums (PR 87286)

Browse Source 
We've traditionally allowed vectors of enums (not sure if that's
deliberate) but vector_types_compatible_elements_p checked for
INTEGER_TYPE rather than INTEGRAL_TYPE_P.

	PR c/87286
	* c-common.c (vector_types_compatible_elements_p): Use
	INTEGRAL_TYPE_P instead of checking only for INTEGER_TYPE.
