Actually I don't almost touch pyssvp64asm, these two ways of assembly co-exist
for now: the choice of backend is done via INSNDB environment variable. Once I
feel I covered most of these, I'll proceed with testing and dropping the
legacy. I think that eventually everything in assembly will be done by new
backend, and we will only keep macros and "lexing" in pysvp64asm. I
intentionally skip the testing for now, because almost everything is expected
to fail at this point, since we don't have all specifiers supported.

Yes, this is one of the goals ultimately, it's just that I have not that much
to test yet, since most of disassembly tests use specifiers extensively. But,
once these are ready, I will populate them.
