PR middle-end/64928
* tree-ssa-live.h (struct tree_live_info_d): Add livein_obstack
and liveout_obstack members.
(calculate_live_on_exit): Remove.
(calculate_live_ranges): Change declaration.
* tree-ssa-live.c (liveness_bitmap_obstack): Remove global var.
(new_tree_live_info): Adjust.
(calculate_live_ranges): Delete livein when not wanted.
(calculate_live_ranges): Do not initialize liveness_bitmap_obstack.
Deal with partly deleted live info.
(loe_visit_block): Remove temporary bitmap by using
bitmap_ior_and_compl_into.
(live_worklist): Adjust accordingly.
(calculate_live_on_exit): Make static.
* tree-ssa-coalesce.c (coalesce_ssa_name): Tell calculate_live_ranges
we do not need livein.
