PR middle-end/54146
* tree-flow.h (compute_global_livein): Remove prototype.
* tree-into-ssa.c (compute_global_livein): Remove function.
* tree-ssa-loop-manip.c: Include gimple-pretty-print.h.
(find_sibling_superloop): New function.
(compute_live_loop_exits): New function.
(add_exit_phis_edge): Rename to add_exit_phi. Do not allow
inserting a PHI in a block that is not a loop exit for VAR.
Add dumping if TDF_DETAILS.
(add_exit_phis_var): Rewrite.
(add_exit_phis): Update.
(get_loops_exits): Rewrite to return an array of per-loop exits
rather than one bitmap with all loop exits.
(find_uses_to_rename_bb): Ignore virtual PHI nodes.
(rewrite_into_loop_closed_ssa): Update.
