VirtRegMap: Correctly deal with bundles when deleting identity copies.
This fixes two problems when VirtRegMap encounters bundles:
- When substituting a vreg subregister def with an actual register the
internal read flag must be cleared.
- Removing an identity COPY from a bundle needs to use
removeFromBundle() and a newly introduced function to update
SlotIndexes.
No testcase here, because none of the in-tree targets trigger this,
however an upcoming commit of mine will need this and the testcase there
will trigger this.
