Which means, the live-out bonus instructions must be exclusively used

which will then be successfully updated to recieve cloned bonus instns.

[Hexagon] Reconsider getMask fix, return original mask, convert later

that could be composed into a masked load/store without any additional
type casts. The previous fix violated that.
Instead, convert scalar mask to a vector right before rescaling.
