* tree-ssa-propagate.c (add_ssa_edge): Dump what edge list we
add which use to.
(add_control_edge): Remove excessive vertical space in dumping.
(process_ssa_edge_worklist): Simulate at most one statement and
return whether we did. Do not simulate PHIs if they are in a
BB not yet simulated.
(ssa_propagate): Adjust to always drain the BB worklist whenever
a BB is available there, likewise the VARYING edges list before
the interesting edge list.
