* passes.c (init_optimization_passes): Replace copy propagation
passes immediately after DOM with phi-only copy propagation
pases. Add phi-only copy propagation pass after first DOM pass.

* tree-ssa-copy.c (init_copy_prop): Accept new PHI_ONLY argument.
If true, then mark all non-control statements with DONT_SIMULATE_AGAIN.
(execute_copy_prop): Accept new PHI_ONLY argument. Pass it along
to init_copy_prop. Callers updated.
(do_phi_only_copy_prop): New function.
(pass_phi_only_copy_prop): New pass descriptor.
