TwoAddressInstructionPass: Trigger -O0 behavior on optnone
While we cannot skip the whole TwoAddressInstructionPass even for -O0
there are some parts of the pass that are currently skipped at -O0 but
not for optnone. Changing this as there is no reason to have those two
hit different code paths here.
