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.
