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

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.

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