Of course. That's why I thought James was talking about enabling vector modes
and the corresponding move patterns unconditionally, and only conditionalizing
the VIS-specific insns on -mvis. Currently (well, once my upcoming patch is
applied), we have no vector modes with -mno-vis, yet the appropriate
load/store instructions are generated for vector types and the calling
conventions are the same as with -mvis.
