Overhaul of everything phi related; critical edge splitting now happens before
...
anything SSA happens; liveness calculations now look like they might be
working.

Better constraint syntax; mcgg now passes register usage information up to mcg;
...
mcg can track individual hop inputs and outputs (needed for live range
analysis!); the register allocator now puts the basic blocks into the right
order in preparation for live range analysis.

Made sure that all files end in vim magic.

Get quite a long way towards basic output-register equality constraints (needed
...
to make special nodes like NOP work properly). Realise that the way I'm dealing
with the instruction selector is all wrong; I need to physically copy chunks of
tree to give to burg (so I can terminate them correctly).

Much better handling of fragments (no run-time code needed to distinguish them
...
from registers) and better handling of individual hops within a paragraph ---
no more ghastly hacks to try and distinguish the input from the output.

Actually, I don't need vregs: hops work just as well. Particularly if I
...
restructure things so that I don't need to walk the blasted ir / burg tree
every time I look at an instruction.

Fleshed out hops and vregs. The result is almost looking like code now ---
...
uncanny.

Start factoring out the hardware op code.
