romcc

[Eric W. Biederman]

After a lot of pound the code generator seems stable, and I can take
a break to release romcc.

Currently it appears that any time it completes without error
the code generated is correct.

And most importantly with a few minor tweaks it compiles the
code written for l440gx memory initialization, before the compiler
was written.

Currently ``constant propagation'', ineffectual code elimination (code
that does not affect the output), a good register allocator and always
inlining are the only optimizations implemented.  

On the wishlist are:
- using the mmx & sse registers on x86.
- x86-64 and Itanium ports.
- struct support
- non string constant initializers.
- A bibliography.

But it should be good enough to start playing with.
The version gets to be 1.0 when the compiler is useful enough to
compile a LinuxBIOS port.
