  Log Message:
  -----------
  [Test] Add XFAIL test for PR56243

This test demonstrates how sinking down gc.relocate may lead to breach
of LCSSA form by tokens and, consecutively, end up with SSA breach by
LoopSimplifyCFG which creates fake edges and is unable to update missing
LCSSA phis for tokens used outside of the loop.
