[InlineFunction] Correctly inline TerminatePadInst

We forgot to append the terminatepad's arguments which resulted in us
treating the old terminatepad as an argument to the new terminatepad
causing us to crash immediately.  Instead, add the old terminatepad's
arguments to the new terminatepad.

This fixes PR25155.
