For the first project, I think you should understand the LLVM IR and how 
to use the C++ API (e.g., the IRBuilder class) to create and manipulate 
the IR.  If you can write a simple LLVM pass, that would be a good start.

For the second project, I'm not really sure.  You should look at the 
existing work and see if it transforms code at the LLVM IR level or the 
MachineIntr level (i.e., is it a ModulePass/FunctionPass or a 
MachineFunctionPass?).  That will guide you on what background you need.

Just out of curiosity, why the interest in Forth?
