This is the initial release of the self-hosted compiler.

It's still in a very unpolished state, but you can use it to bootstrap itself.

Just run the script "util/bootstrap.py":

$ python util/bootstrap.py

Which does the following:
1) run gcc on the distributed version of self/compile.c
2) this binary will be used to recompile the compiler.
3) that binary will recompile the compiler again.
4) the output from steps 2 and 3 are compared, they should be identical.

If you're happy with the resulting compiler, you can compile an optimized
version of self/compile.c, but be warned - you'll need a lot of memory and
a lot of time.

I am using dragonegg for optimized builds, and that seems to take about a GB
of memory, and 18 minutes to build.  It's important to use '-O2', not '-O',
because '-O' takes 53GB of memory and hours to compile.

Very little documentation exists yet, try 'lang.html' for a brief tutorial.
The best way to get familiar with the language is to read the source code in
the 'self' directory, and browse over the files in "tests".

110326 Release Note: there is currently something very wrong with the
combination of recursive types and rows, which shows up when using the
new 'OO-like' feature (the '::' syntax).  It seems to be completely
destroying all type safety.  So for now just stay away from that stuff
until I can figure out what's going wrong.
