Yes as far as the version that we currently have imported, but no if we were to
update vixl.  In particular, capstone has no support for SVE or other v8.2+
additions.

We could definitely lose the old x86 disassembler.  Which has no support for
AVX, which we use in TCG.  Possibly some of the others too, but not many.

It might be worthwhile, yes.

I don't know what the level of difficulty is there.

I certainly do not thing a complete new standalone disassembler is worthwhile.
 Exactly what to suggest instead is a problem though.
