Fall back to masked_gather_load/masked_scatter_store
This adds a fallback to the masked_ variants for gather_load
and scatter_store if the latter are not available.
2021-08-17 Richard Biener <rguenther@suse.de>
* optabs-query.c (supports_vec_gather_load_p): Also check
for masked optabs.
(supports_vec_scatter_store_p): Likewise.
* tree-vect-data-refs.c (vect_gather_scatter_fn_p): Fall
back to masked variants if non-masked are not supported.
* tree-vect-patterns.c (vect_recog_gather_scatter_pattern):
When we need to use masked gather/scatter but do not have
a mask set up a constant true one.
* tree-vect-stmts.c (vect_check_scalar_mask): Also allow
non-SSA_NAME masks.
