Hmm. Moving it into InitFIR.cpp creates circular dependencies: it calls registration functions from FIRCodeGen, HLFIRTransforms, etc - all of which depend on FIRSupport. I'd need to create a new library just for this change. I agree it would be aesthetically pleasing to keep it the same as registerLLVMTranslation right below this, but it's proving to be a mess.
