jhenderson added a subscriber: labath.

Previously, if an extended opcode was truncated, it would manifest as an "unexpected line op length error" which wasn't quite accurate. This change checks for errors any time data is read whilst parsing an extended opcode, and reports any errors detected.

Depends on D80796 <https://reviews.llvm.org/D80796>.
