Step by step, please :)

Step 1 is to build something that works.
Step 2 is to build something that works faster.

We didn't finish step 1 yet (although I successfully compiled and ran
a `hello world' style program today).  When that is done, we'll have
to teach gcc how to output the `register usage hints' and fast entry
points that we need for link-time register renaming, and build a linker
that supports them.  But first the compiler must learn how to generate
correct code - some things are still broken.
