The current 3.7 code breaks for the codebase that I use for teaching.  It uses RTTI in the AST construction, so can’t be compiled with -fno-rtti, but does need to use Module, IRBuilder, and friends, so not being able to link against an LLVM that’s built without RTTI is annoying (it means that the students can’t use LLVM packages on any OS).
