[PATCH] Move code out of tree-ssa-dom into tree-ssa-scopedtables

        PR tree-optimization/47679
        * tree-ssa-dom.c (enum expr_kind): Moved from here to
        tree-ssa-scopedtables.h.
        (struct hashable_expr, class expr_hash_elt): Likewise.
        (struct expr_elt_hasher, class avail_exprs_stack): Likewise.
        Move associated methods into tree-ssa-scopedtables.c.
        (avail_expr_hash, initialize_expr_from_cond): Similarly.
        (hashable_expr_equal_p, add_expr_commutative): Likewise.
        (add_hashable_expr): Likewise.
        (record_cond): Delete element directly.
        * tree-ssa-scopedtables.h (avail_expr_stack, const_and_copies): Add
        private copy ctor and assignment operator methods.
        (expr_elt_hasher): Inline trivial methods.
        (initialize_expr_from_cond): Prototype.
        * tree-ssa-scopedtables.c: Add necessary includes, functions and
        methods that were previously in tree-ssa-dom.c.  Improve various
        comments.
