tree-optimization/116796 - virtual LC SSA broken after unrolling
When the unroller unloops loops it tracks whether it changes any
nesting relationship of remaining loops but when scanning a loops
preheader it fails to pass down the LC-SSA-invalidated bitmap, losing
the fact that an unrolled formerly inner loop can now be placed on
an exit of its outer loop. The following fixes that.
PR tree-optimization/116796
* cfgloopmanip.cc (fix_loop_placements): Get LC-SSA-invalidated
bitmap and pass it on.
(remove_path): Pass LC-SSA-invalidated to fix_loop_placements.
