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.

2022-02-11  Richard Biener  <rguenther@suse.de>

	PR middle-end/104496
	* internal-fn.cc (vectorized_internal_fn_supported_p):
	Bail out for integer mode vector types.

	* gcc.target/i386/pr104496.c: New testcase.
