Unfortunately not so good, please find a correction attached. Also
this adds proper type information, takes care of the optimisation
in the compiler when possible, and adds the "test suite" to make
check.

Also make-promise is now exported in the chicken egg. I am not sure
whether we should place it there but it seems more convenient than
to provide a r7rs-core thing you need to import as well...

Thanks for bearing with me,

Christian
