Convert Ophis to Python 3.
...
Most of the work is handled by 2to3, but there's a few extra tricks
needed to finish the job, mostly about picking the right bits to be
Unicode and the right bits to be bytes.

added to the test case files, but isn't directly checked as part
of verification.

Rework label map collection
...
This uses a pass to interrogate the system for locations, then dumps
those out instead. It handles includes, anonymous labels, and basic
macros, but it does so in a somewhat ugly way. This data can be
readily abbreviated and should also be re-sorted.

Bugfix: Let Collapse Pass reverse collapses

label past the zero-page boundary.

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 continues with the older, more efficient behavior.

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).
