Massive change to how IR types are handled; we use the type code for matching
...
rather than the size. Much cleaner and simpler.

Remove GETRET; values are now returned directly by CALL. Fix a bug in
...
convertstackops which was resulting in duplicate IR groups.

Stop passing proc around, and use a global instead --- much cleaner.

Fix bug where pushes were being placed in the wrong blocks.

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

Refactor the cfg and dominance stuff to make it a lot nicer.

Perform SSA conversion of locals. Much, *much* better code now, at least
...
inasmuch as it looks better before register allocation. Basic blocks now know
their own successors and predecessors (after a certain point in the IR
processing).

Fix edge case where leftover pushes would occasionally cause infinite loops in
...
the analysis.

More rigorous dealing of IR groups; no need for is_generated and is_root any
...
more (but now passes are required to set IR roots properly when changing
instructions).

It doesn't really make a lot of sense to have BURG nonterminal names different
...
to register classes, so combine them. Refactor the map code.

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.

Revamp the array module not to use nasty macros any more. Slightly more verbose
...
to use, but definitely cleaner.

Replaced the block splicer with a trivial block eliminator (which rewrites
...
jumps to blocks which contain only a jump). Don't bother storing the bb graph
in the ir nodes; we can find it on demand by walking the tree instead ---
slower, but much easier to understand and more robust. Added a terrible map
library.

Each pass now lives in its own source file; much cleaner.
