From: Ju-Zhe Zhong <juzhe.zhong@rivai.ai>

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
