Fix profile update after RTL unrolling
This patch fixes profile update after RTL unroll, that is now done same way as
in tree one. We still produce (slightly) corrupted profile for multiple exit
loops I can try to fix incrementally.
I also updated testcases to look for profile mismatches so they do not creep
back in again.
gcc/ChangeLog:
* cfgloop.h (single_dom_exit): Declare.
* cfgloopmanip.h (update_exit_probability_after_unrolling): Declare.
* cfgrtl.cc (struct cfg_hooks): Fix comment.
* loop-unroll.cc (unroll_loop_constant_iterations): Update exit edge.
* tree-ssa-loop-ivopts.h (single_dom_exit): Do not declare it here.
* tree-ssa-loop-manip.cc (update_exit_probability_after_unrolling):
Break out from ...
(tree_transform_and_unroll_loop): ... here;
