Allow fully masked loops with legacy gather/scatter
The following removes the redundant check on supported gather/scatter
IFN in check_load_store_for_partial_vectors which is already done
and adjusts those to check the recorded ifn, also allowing legacy
gather/scatter which all handle masking.
* tree-vect-stmts.cc (check_load_store_for_partial_vectors):
Remove redundant gather/scatter target support check, instead
check the recorded ifns. Also allow legacy gather/scatter
with loop masking.
* gcc.dg/vect/vect-gather-1.c: Adjust to hide N.
