Change subject: arch: Make the DummyVec... types the same size as RegVal.
......................................................................
arch: Make the DummyVec... types the same size as RegVal.
This makes RegClass-es which don't specify a size work with the Dummy
types of VecRegContainer and VecPredRegContainer, and avoids having to
set up extra plumbing in ISAs that don't need it.
