The older disas/arch.c files come from binutils, prior to the GPLv3 license change.  These 
are generally very old architectures, or not up to date.

The newer target/arch/disas.c are for architectures for which the translator and the 
disassembler share generated code via decodetree.  If you're implementing a new 
architecture from scratch, this is your best choice.

The "best" supported are those with support in system libcapstone.  :-)
