According to
https://bugzilla.redhat.com/show_bug.cgi?id=2127503
bleeding-edge clang complains thusly:
llvmjit_inline.cpp: In function 'std::unique_ptr<llvm::ModuleSummaryIndex> llvm_load_summary(llvm::StringRef)':

I suspect this is less about clang and more about LLVM APIs,
but anyway it seems like we gotta fix something.
