(lookup_avail_expr, build_and_record_new_cond): Likewise. (record_conditions, record_cond, vuse_eq): Likewise. (record_edge_info): Adjust to API tweak of record_conditions. (simplify_stmt_for_jump_threading): Similarly for lookup_avail_expr. (record_temporary_equivalences, optimize_stmt): Likewise. (eliminate_redundant_computations): Likewise. (record_equivalences_from_stmt): Likewise. * tree-ssa-scopedtables.c: Include options.h and params.h. (vuse_eq): New function, moved from tree-ssa-dom.c (build_and_record_new_cond): Likewise. (record_conditions): Likewise. Accept vector of conditions rather than edge_equivalence structure for first argument. for the first argument. (avail_exprs_stack::lookup_avail_expr): New member function, moved from tree-ssa-dom.c. (avail_exprs_stack::record_cond): Likewise. * tree-ssa-scopedtables.h (struct cond_equivalence): Moved here from tree-ssa-dom.c. (avail_exprs_stack): Add new member functions lookup_avail_expr and record_cond. (record_conditions): Declare.
