aco/lower_branches: implement try_remove_simple_block() in lower_branches()
This is mostly the same as in jump_threading, but can handle
multiple predecessors.

aco/lower_branches: remove edges between blocks if there is no direct branch
This way, linear predecessors and successors better reflect the
actual control flow which improves wait state insertion and hazard
mitigation.
