re PR tree-optimization/71437 (Performance regression after r235817)
PR tree-optimization/71437
* tree-ssa-dom.c (pfn_simplify): Add basic_block argument. All
callers changed.
(simplify_stmt_for_jump_threading): Add basic_block argument. All
callers changed.
(lhs_of_dominating_assert): Moved from here into tree-vrp.c.
(dom_opt_dom_walker::thread_across_edge): Remove
handle_dominating_asserts argument. All callers changed.
(record_temporary_equivalences_from_stmts_at_dest): Corresponding
changes. Remove calls to lhs_of_dominating_assert. Other
uses of handle_dominating_asserts turn into unconditional code
(simplify_control_stmt_condition_1): Likewise.
(simplify_control_stmt_condition): Likewise.
(thread_through_normal_block, thread_across_edge): Likewise.
* tree-ssa-threadedge.h (thread_across_edge): Corresponding changes.
* tree-vrp.c (lhs_of_dominating_assert): Move here. Return original
object if it is not an SSA_NAME.
(simplify_stmt_for_jump_threading): Call lhs_of_dominating_assert
before calling into the VRP specific simplifiers.
(identify_jump_threads): Remove handle_dominating_asserts
argument.
