* tree-ssa-pre.c (eliminate_dom_walker::before_dom_children):
Skip unreachable blocks and destinations.
(eliminate): Move stmt removal and fixup ...
(fini_eliminate): ... here. Skip inserted exprs.
(pass_pre::execute): Move fini_pre after fini_eliminate.
* tree-ssa-tailmerge.c: Include tree-cfgcleanup.h.
(tail_merge_optimize): Run cleanup_tree_cfg if requested by
PRE to get rid of dead code that has invalid SSA form and
split critical edges again.
