    middle-end/104496 - fix vectorized_internal_fn_supported_p
    
    This fixes vectorized_internal_fn_supported_p behavior when
    facing vector types with an integer mode.

            * internal-fn.cc (vectorized_internal_fn_supported_p):
            Bail out for integer mode vector types.
    
            * gcc.target/i386/pr104496.c: New testcase.
