Andy McFadden 478afa542e Fix 64tass code gen corner case ...

On the 65816, if you say "JSR foo" from bank $12, but "foo" is an
address in bank 0, most assemblers will conclude that you're forming
a 16-bit argument with a 16-bit address and assemble happily.  64tass
halts with an error.  Up until v1.55 or so, you could fake it out
by supplying a large offset.

This no longer works.  The preferred way to say "no really I mean to
do this" is to append ",k" to the operand.  We now do that as needed.

I didn't want to define a new ExpressionMode for 64tass just to
support an operand modifier that should probably never actually get
generated (you can't call across banks with JSR!), so this is
implemented with a quirk and an op flag.

64tass v1.56.2625 is now the default.
