[PATCH] rs6000: Fix use of wrong enum for built-in function code.

[Bill Schmidt via Gcc-patches]

Hi!

I discovered this bug while working on patches to remove the old built-ins
infrastructure.  I missed a spot in converting from the rs6000_builtins enum to
the rs6000_gen_builtins enum.  This fixes it.  The fix is technically not right
if new_builtins_are_enabled were to be set to zero, but we're not going to do
that anymore, and the remnants of that code will be removed shortly.

Regstrap is in progress on powerpc64le-linux-gnu.  Assuming no problems, is this
okay to commit to trunk?

Thanks!
Bill
