[v3,1/2] Record ARM THUMB2 PLD/PLI cache instructions
Commit Message
These weren't decoded correctly and trigger an unknown instruction error
when recording. The ARM format was handled, but not the 32-bit THUMB2
format.
Since they are only hints that may affect cache state, there is nothing
to record.
