This revision is now accepted and ready to land.

There's missing context in the review description which is important.  Please add something along the lines of the following.

The currently ratified calling convention in psABI does not support passing vector arguments or return values in registers.  LLVM implements a non-standard calling convention for vector arguments and returns.  psABI requires that such non-standard calling conventions be tagged w/ .variant_cc.

With that additional context, LGTM.
