Allowing an input filename on the command line makes debuggers happy. (Then we
...
don't need to redirect stdin.)

Fix the horror of the startup code; now uses getopt and stuff and the debug
...
flags can be set as an option.

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).

Move fatal(), warning() and aprintf() into the new data module (because they're
...
really useful).

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

Some instruction selection is now happening.

Procedure compilation now happens after the entire EM file has been read in (so
...
that we can look inside data blocks which might be defined in the future...
sigh, csa and csb). csa and csb no longer generate invalid IR.

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.
