Add support for storing code model to LLVM module IR
This patch avoids undefined behavior by linking different object files. Also this would it could be propagated properly to LTO. See https://reviews.llvm.org/D52322 and https://reviews.llvm.org/D52323. This patch is based on https://github.com/rust-lang/rust/pull/74002
