Nicolai Haehnle 283b995097 AMDGPU: Fix getInstSizeInBytes 
Summary:
Add some optional code to validate getInstSizeInBytes for emitted
instructions. This flushed out some issues which are fixed by this
patch:

- Streamline getInstSizeInBytes
- Properly define the VI readlane/writelane instruction as VOP3
- Fix the inline constant determination. Specifically, this change
  fixes an issue where a 32-bit value of 0xffffffff was recorded
  as unsigned. This is equal to -1 when restricting to a 32-bit
  comparison, and an inline constant can be used.
