re PR tree-optimization/61289 (Bad jump threading generates infinite loop)
PR tree-optimization/61289
* tree-ssa-threadedge.c (invalidate_equivalences): Remove SRC_MAP and
DST_MAP parameters. Invalidate by walking all the SSA_NAME_VALUES
looking for those which match LHS. All callers changed.
(record_temporary_equivalences_from_phis): Remove SRC_MAP and DST_MAP
parameters and code which manipulated them. All callers changed.
(record_temporary_equivalences_from_stmts_at_dest): Remove SRC_MAP
and DST_MAP parameters. Simplify invalidation code by just calling
invalidate_equivalences. All callers changed.
(thread_across_edge): Simplify now that we don't need to maintain
the map of equivalences to invalidate.
