commit r14-2016-g4b23d10ce8c7015c19e911324602633c36a2b828

    Move can_vec_mask_load_store_p and get_len_load_store_mode from "optabs-query" into "optabs-tree"
    
    Since we want both can_vec_mask_load_store_p and get_len_load_store_mode
    can see "internal_fn", move these 2 functions into optabs-tree.
    
    gcc/ChangeLog:
    
            * optabs-query.cc (can_vec_mask_load_store_p): Move to optabs-tree.cc.
            (get_len_load_store_mode): Ditto.
            * optabs-query.h (can_vec_mask_load_store_p): Move to optabs-tree.h.
            (get_len_load_store_mode): Ditto.
            * optabs-tree.cc (can_vec_mask_load_store_p): New function.
            (get_len_load_store_mode): Ditto.
            * optabs-tree.h (can_vec_mask_load_store_p): Ditto.
            (get_len_load_store_mode): Ditto.
            * tree-if-conv.cc: include optabs-tree instead of optabs-query
