llvm-wrapper: fix few warnings Two fixes: first one is simple unsigned -> uint64_t, but how second one is more subtile, see commit description.
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
