Nuke bind expressions.
...
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

Link a bool to its block rather than the block's head.

This makes the flow make a little more sense.

Print expressions as dot files.

While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.

Get basic function creation working.

Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
...
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.

Add symbol expressions (like def expressions).

They will eventually replace def expressions. Currently quite broken.

Produce nicer code for post-op.
...
The temp notice is still there for arrays (that's caused by issues in
constfold.c, not easily fixilbe), but it's harmless and correct (and nice)
code is much more important.

Swap the order of scale and base for calculating the array index.
...
fold_constants doesn't like dags very much, but it can do the right thing
if the expressions are in the right order. This is merely a workaround
until I get to work on the code generator itself.

Rework class_type_t to be more useful.

reporting).

Produce slightly better v6 modulo code for complex inputs.
...
I'm having problems with temp defs, but I imagine this code is rarely used
so I won't worry about it for now. It will, however, make a good test case
for when I rework emit.c after I do some reading.

v6 modulo implementation now produces good code.

At least for simple inputs, anyway. That needs to be tested next.

Rewrite the v6 modulo implementation.

While trying to understand bind expressions, I discovered that the v6
modulo code was incorrect. This version is correct but uses one too many
temps. That's next.

the relevant sentences are now much easier to read.
