API change in StackVisitor::GetVReg*.

- Remove GetVReg() and SetVReg() that were expecting to always succeed.
- Change Quick-only methods to take a FromQuickCode suffix.
- Change deopt to use dead values when GetVReg does not succeed:
  the optimizing compiler will not have a location for uninitialized
  Dex registers and potentially dead registers.
