[PATCH] [AArch64] Fix problems in handling generic MSR/MRS instructions

[Petr Pavlu]

Hi James,

Thank you for the review. The rewrite happens in a `DecoderMethod` of the `MSRpstate` instrution, not in a `DecoderMethod` of an operand, so there should be no assumption it is the last operand to be decoded.

However, thanks for confirming there is currently not a good way how to implement this cleanly without modifying TableGen parts. I will have a look what could be done to support this case but it will probably take me some time to get to it.

Petr
