This would be the equivalent to the existing llvm::hasGlobalValueSummary() function, which currently controls whether we compile a module with regular LTO or with ThinLTO.

Note that the module summary already covers all global values, not just functions. >> std::unique_ptr<Module> M1 = R.getLazyModule(C...
