Subject: Use sail_lib.lem values in C backend

Rather than just using strings to represent literals, now use value
types from sail_lib.lem to represent them. This allows for expressions
to be evaluated at compile time, which will be useful for future
optimisations involving constant folding and propagation, and allows
the intermediate bytecode to be interpreted using the same lem
builtins that the shallow embedding uses.

To get this to work I had to tweak the build process slightly to allow
ml files to import lem files from gen_lib/. Hopefully this doesn't
break anything!
