PHIOPT: Allow other diamond uses when do_hoist_loads is true
While working on adding diamond shaped form to match-and-simplify
phiopt, I Noticed that we would not reach there if do_hoist_loads
was true. In the original code before the cleanups it was not
obvious why but after I finished the cleanups, it was just a matter
of removing a continue and that is what this patch does.
This just happens also to fix a bug report that I noticed too.
OK? Bootstrapped and tested on x86_64-linux-gnu.
gcc/ChangeLog:
PR tree-optimization/68894
* tree-ssa-phiopt.cc (tree_ssa_phiopt_worker): Remove the
continue for the do_hoist_loads diamond case.
