rs6000: Remove new_builtins_are_live and dead code it was guarding
To allow for a sane switch-over from the old built-in infrastructure to the
new, both sets of code have co-existed, with the enabled one under the control
of the boolean variable new_builtins_are_live. As a first step in removing the
old code, remove this variable and the now-dead code it was guarding.
