[PR87563][AARCH64-SVE]: Don't keep ifcvt loop when COND_<OP> ifn could not be vectorized.
ifcvt will created versioned loop and it will permissively generate
scalar COND_<OP> ifn.
If in the loop vectorize pass, COND_<OP> could not get vectoized,
the if-converted loop should be abandoned when the target doesn't support
such ifn.

* tree-vectorizer.c (try_vectorize_loop_1): Don't use
if-conversioned loop when it contains ifn with types not
supported by backend.
* internal-fn.c (expand_direct_optab_fn): Add an assert.
(direct_internal_fn_supported_p): New helper function.
* internal-fn.h (direct_internal_fn_supported_p): Declare.
