[PATCH] middle-end/104496 - fix vectorized_internal_fn_supported_p

[Richard Biener via Gcc-patches]

This fixes vectorized_internal_fn_supported_p behavior when
facing vector types with an integer mode.

Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

        * internal-fn.cc (vectorized_internal_fn_supported_p):
        Bail out for integer mode vector types.

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