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).

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).

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.

You know what, the type inference stuff is a complete red herring. What this
...
actually needs is a more intelligent register allocator. So, remove the type
inference.

Keep more data around about ir instructions. Implement a half-baked type
...
inference routine to propagate information about floats up the tree, so we know
whether to put floats into special registers as early as possible.

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.

Add a bodged in algorithm for converting basic block communication from stacked
...
variables to SSA. Also add dead block removal and block splicing. IR code is
much better now.

Tracing cleanup. Simplified the IR code. Some more opcodes.

Store the EM code up front and build the basic block graph *before*
...
generating the IR code. Lots more IR code.
