Description
The C code generation stuff is a terrible, rotten mess. It's incomprehensible and making changes in the code has become rather difficult. I have a "backend" branch that uses an intermediate representation (S-expressions, roughly C-like), originally intended for an alternative backend ("qbe") that seems to work, at least for the core system + tests.
I can try to bring it up to date and present it once it is ready.

Looks like we can make this work for 5.4; too big a change for 5.3

It"s nearly working. There is still a problem with foreign-type-size that needs to be solved.

I've pushed the current state with all changes from master to the branch "backend". I'll need to do some more tests and then we can decide how to go on. Comments are welcome.
