Oh... why do I need to rebase?
I don't have the manpower or C++ expertise to hack on LLVM itself, I've 
been planning to just use it. Since I'm just doing a proof of concept, I 
(hopefully) won't have to use any of the more experimental stuff.

A different but related questons: Are minor releases of LLVM 
backwards-compatible? Bitcode compatibility would be particularly 
interesting - can I assume that the LLVM toolchain is able to work with 
bitcode generated by earlier versions of the toolchain?
