tree-optimization/93094 pass down VECTORIZED_CALL to versioning
When versioning is run the IL is already mangled and finding
a VECTORIZED_CALL IFN can fail.

PR tree-optimization/93094
* tree-vectorizer.h (vect_loop_versioning): Adjust.
(vect_transform_loop): Likewise.
* tree-vectorizer.c (try_vectorize_loop_1): Pass down
loop_vectorized_call to vect_transform_loop.
* tree-vect-loop.c (vect_transform_loop): Pass down
loop_vectorized_call to vect_loop_versioning.
* tree-vect-loop-manip.c (vect_loop_versioning): Use
the earlier discovered loop_vectorized_call.
* gcc.dg/vect/pr93094.c: New testcase.
