  Log Message:
  -----------
  [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.
