- Sort the coordinates and operands in the same order as for the SPIR-V
  instructions.
- Renamed 'q' to 'dRef'.
- Used integer type for offset operands.
- Renamed 'addressingModeY' to 'addressingModeA'. Note this is only used
  by cube array coordinates. 2D array coordinates use 'addressingModeW'
  at the moment.
- Removed array layer coordinate parameter from 3D sampling.
- Added 'dRef' operand for 3D sampling.
