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 .

Fix codemodels.c test case (only test mcmodel-kernel on x86) A recent commit I made broke aarch64 testing, because "kernel" apparently is not a valid code-model on aarch64, and one of my tests tested that. This fixes the problem (hopefully) by adding "-triple x86_64-unknown-linux-gnu" to the test build with "-mcodel-model kernel". Differential Revision: https://reviews.llvm.org/D52383 llvm-svn: 342789

Fix codemodels.c test case (only test mcmodel=medium on X86). aarch64 testing is broken because "medium" is not a valid code-model on aarch64, and codemodels.c tests that. This fixes that problem by adding "-triple x86_64-unknown-linux-gnu" to the test with "-mcode-model moedium". llvm-svn: 342812
