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.

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.

Create hacky fake basic blocks for data fragments, used to track which
...
instruction labels descriptor blocks refer to; this allows csa and csb to know
where they're going.

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