* tree-flow.h (rename_variables_in_loop): Remove.
(rename_variables_in_bb): Likewise.
* tree-loop-distribution.c (update_phis_for_loop_copy): Remove.
(copy_loop_before): Adjust and delete update-ssa status.
* tree-vect-loop-manip.c (rename_variables_in_bb): Make static.
(rename_variables_in_bb): Likewise. Properly walk over
predecessors.
(rename_variables_in_loop): Remove.
(slpeel_update_phis_for_duplicate_loop): Likewise.
(slpeel_tree_duplicate_loop_to_edge_cfg): Handle nested loops,
use available cfg machinery instead of duplicating it.
Update PHI nodes and perform poor-mans SSA update here.
(slpeel_tree_peel_loop_to_edge): Adjust.
* gcc.dg/torture/pr55964.c: New testcase.
