LLVM can bet a very good optimized compiler toolchain, but is complex, hard to use and break easily (your code). I have tried to use it several times for toy compilers, and each time is a pain for do simple things. I can't imagine how much pain is for depend your project on it. Certainly worth the effort, but as expected of a C++ tech: You need a army of specialist to make it work.
