Wait what? We're not ratifying without temporal safety support! |

don't worry - we definitely will - but we need more time to resolve issues with Svucrg before it's ready for freeze - that can be in another PR |

Done:
Combine and rename CHERI load page faults into a single lowest priority fault (fix #923)
Remove Svucrglct - require exception when tag is set, allow exception when tag not set, no change in exception priority for the different cases (fix #915)
Update all exception tables to show updated priority (includes fix #924)
Add rule about allowing SC.Y to set PTE.CD even if the store fails
Add notes about (future) AMOCAS.Y (if rs2.tag=1), AMOADD.Y (always) to set CD even if the store fails
Add rule/notes about ensuring CD may be set too often, and load capability faults may fire too often
