Looks pretty impressive already.

I wanted to take it for a spin, but got errors about the following
symbols being missing:

LLVMOrcUnregisterPerf
LLVMOrcRegisterGDB
LLVMOrcRegisterPerf
LLVMOrcGetSymbolAddressIn
LLVMLinkModules2Needed

As far as I can tell these are not in mainline LLVM. Is there a branch
or patchset of LLVM available somewhere that I need to use this?
