What I had in mind was to have a callback in case the parsing fails
with "invalid instruction for ARM/Thumb" and _realise_ we're in the
wrong encoding.

But again, if the user wants to write Thumb code in inline assembly,
using encoding modifiers would be the expected behaviour, so even that
would be correcting bad user behaviour.

Enhancement at best...
