Add necessary support for storing code-model to module IR. Currently the code-model does not get saved in the module IR, so if a code model is specified when compiling with LTO, it gets lost and is not propagated properly to LTO. This patch does what is necessary in the front end to pass the code-model to the module, so that the back end can store it in the Module . Differential Revision: https://reviews.llvm.org/D52323 llvm-svn: 342758
