Updated based off some conversation with Amara offline.

- Taught BUILD_VECTOR about unpacked vectors, where it could previously screw up in the old version of the patch
- Added some more validation to selectCopy
- Generalized the subregister insert case in selectCopy
- Added a `getMinClassForRegBank` convenience function to handle the cross-bank copies in selectCopy
