tree-optimization/106860 - fix profile scaling in split_loop
The following fixes a mistake in loop splitting which assumes loop
latches have a single predecessor and that edge is from the exit
test. Instead work from the single exit edge we have to find the
edge towards the latch.
PR tree-optimization/106860
* tree-ssa-loop-split.cc (split_loop): Find the exit to
latch edge from the loop exit edge instead of from the
latch. Verify we're going to find it.
* g++.dg/opt/pr106860.C: New testcase.
