Simon Moll 351c10cc72 [VE] Add +vpu attribute
`+vpu` controls whether VEISelLowering adds any vregs.  This defaults to
`-vpu` to have scalar code generation out of the box.  We bring up
vector isel under the `+vpu` flag. Once vector isel is stable we switch
to `+vpu` and advertise vregs and vops in TTI.
