Don't tail-merge blocks from different loops

2017-07-03  Tom de Vries  <tom@codesourcery.com>

PR tree-optimization/81192
* tree-ssa-tail-merge.c (same_succ_hash): Use bb->loop_father->num in
hash.
(same_succ::equal): Don't find bbs to be equal if bb->loop_father
differs.
(find_same_succ_bb): Remove obsolete test on bb->loop_father->latch.

* gcc.dg/pr81192.c: Update.
