* tree-vrp.c (evrp_dom_walker::before_dom_children): Ignore
backedges when identifying the single predecessor to take
conditional info from. Use SCEV to get at ranges for loop IVs.
* lto-streamer-out.c (lto_write_mode_table): CSE inner mode to
avoid false warning.
* gcc.dg/tree-ssa/cunroll-13.c: Disable EVRP.
* gcc.dg/tree-ssa/pr21458.c: Likewise.
* gcc.dg/tree-ssa/pr21458-2.c: New testcase for EVRP.
