tree-optimization/103990 - fix CFG cleanup regression from PRE change
This adjusts the CFG cleanup flow back to what it was before the
last change which fixes the observed regression of 541.leela_r with
LTO and FDO.

PR tree-optimization/103990
* tree-pass.h (tail_merge_optimize): Drop unused argument.
* tree-ssa-tail-merge.c (tail_merge_optimize): Likewise.
* tree-ssa-pre.c (pass_pre::execute): Retain TODO_cleanup_cfg
and adjust call to tail_merge_optimize.
