This function can be invoked on VECTOR_TYPE, but the implementation
assumes it works on integer types only. To fix, added a check whether
the type passed is any `__vector(T)' or non-integral type, and return
early by calling `signed_or_unsigned_type_for()' instead.
Problem was found by instrumenting TYPE_PRECISION and ICEing when
applied on VECTOR_TYPEs.
