Sink codegen optimization level into MCCodeGenInfo along side relocation model
and code model. This eliminates the need to pass OptLevel flag all over the place and makes it possible for any codegen pass to use this information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144788 91177308-0d34-0410-b5e6-96231b3b80d8
