Subject: [PATCH, committed] Fix PR 57615, power8 generates an error for -mquad-memory -mno-vsx

I'm committing this as an obvious fix to a thinko on my part.  The problem was
I didn't think about the case where quad memory instructions were available,
but not VSX instructions.  The quad memory support was added to the VSX
implementation of movti for 64-bit, but it wasn't added to the non-VSX
implementation.

I bootstraped it and did a make check comparison with no regressions.

	PR target/57615
	* config/rs6000/rs6000.md (mov<mode>_ppc64): Call
	rs6000_output_move_128bit to handle emitting quad memory
	operations.  Set attribute length to 8 bytes.
