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.
