Second attempt at implementation of the BBXn instructions for Rockwell 65c02 chips.

Reliable technical documentation for how these instructions are decoded is a

Introduce wide-mode override opcodes.
...
This solves the --no-collapse problem by letting you force
Absolute mode on an instruction by instruction bases, which is
usually going to be what you want anyway.

It turns out that --enable-collapse is fundamentally misguided. We'll
need a better solution for that. --no-branch-extension looks pretty good.

Improve .incbin to let its arguments be arbitrary expressions
...
This introduces a new IR node for mutable-during-assembly ranges.

it continues with the older, more efficient behavior.

Merge catseye's incbin-range enhancement.
...
Needed a little work to merge cleanly, but no real surprises.
This isn't a complete solution yet, but it will work for the
basic case. It should allow expressions and gracefully handle
non-hardcoded cases (while still efficiently handling hardcoded
ones).

Wrap up the new file/dir handling.
...
An .outfile directive lets sources suggest default filenames.
Also, .include, .require, .incbin, and .charmapbin are relative
to their _source file_ as opposed the _directory you called Ophis
from_, like it really should have always been.

To account for this change, output files are now prefixed with the
-o option, and if none is specified, it defaults to 'ophis.bin'.
