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).
