Make targetm.get_mask_mode return an opt_mode
...for consistency with mode_for_vector.

* target.def (get_mask_mode): Change return type to opt_mode.
Expand commentary.
* doc/tm.texi: Regenerate.
* targhooks.h (default_get_mask_mode): Return an opt_mode.
* targhooks.c (default_get_mask_mode): Likewise.
* config/i386/i386.c (ix86_get_mask_mode): Likewise.
* optabs-query.c (can_vec_mask_load_store_p): Update use of
targetm.get_mask_mode.
