Pierre-vh added a comment.

- Added note explaining how instructions that write to VPR.P0 work
- Removed the logic to check VPTs, they're acceptable whenever a VCMP is
- Adding VPT before VCTP test case
  - It was causing a crash, which I fixed by adding a null-pointer check at line 404
- Added new debug message at line
