it's doing the usual jobs, Fetch Decode Issue, it's just got quite complex due to SVP64 which is:

* Fetch
* {PrefixDecode FetchSuffix}
* Decode
* {GetPredicate}
* Loop(Issue)

where prefix decode is optional, as is get predicate, and v3.0 scalar instructions are just Loop QTY 1 (one)

inorder.py goes back to straight Power ISA 3.0 and so can reduce down Fetch Decode Issue.

under 500 lines, where dealing with SVP64 is over twice that.
