The jump threading handling in the case of a joiner block was not updating
profile information (it was being updated in the non-joiner case). Added
profile updates for the joiner case, in one place by commoning the
handling between the joiner and non-joiner cases.
Bootstrapped and tested on x86_64-unknown-linux-gnu. Ok for trunk?
Thanks,

* tree-ssa-threadupdate.c (ssa_fix_duplicate_block_edges):
Update redirected out edge count in joiner case.
(ssa_redirect_edges): Common the joiner and non-joiner cases
so that joiner case gets profile updates.
* testsuite/gcc.dg/tree-ssa/ssa-dom-thread-3.c (expand_one_var):
Update for additional dump message.
Thanks for the fix & cleanup. OK for the trunk.
