Refactor disassembly so x86 works, and add x86 transform-dis.

This patch is a monolithic mess, because I was too lazy to do the
refactor first (that would require some stash fun, since I wasn't
actually sure before doing x86 transform-dis what would be needed).

Anyway, the resulting code should be cleaner - less duplication.

This breaks ARM/ARM64.
