This header already includes a CodeGen header and is implemented in lib/CodeGen, so move the header there to match. This fixes a link error with modular codegeneration builds - where a header and its implementation are circularly dependent and so need to be in the same library, not split between two like this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@317379 91177308-0d34-0410-b5e6-96231b3b80d8
