PHIOPT: Improve replace_phi_edge_with_variable's dce_ssa_names slightly
When I added the dce_ssa_names argument, I didn't realize bitmap was a pointer so I used the default argument value as auto_bitmap(). But instead we could just use nullptr and check if it was a nullptr before calling simple_dce_from_worklist. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/ChangeLog: * tree-ssa-phiopt.cc (replace_phi_edge_with_variable): Change the default argument value for dce_ssa_names to nullptr. Check to make sure dce_ssa_names is a non-nullptr before calling simple_dce_from_worklist.
