Avoid setting current_vector_size in get_vec_alignment_for_array_type
The increase_alignment pass was using get_vectype_for_scalar_type
to get the preferred vector type for each array element type.
This has the effect of carrying over the vector size chosen by
the first successful call to all subsequent calls, whereas it seems
more natural to treat each array type independently and pick the
"best" vector type for each element type.

gcc/
* tree-vectorizer.c (get_vec_alignment_for_array_type): Use
get_vectype_for_scalar_type_and_size instead of
get_vectype_for_scalar_type.
