This adds a new API, LTOCodeGenerator::setFileType, to choose the output file format for LTO CodeGen. A corresponding change to use this new API from llvm-lto and a test case is coming in a separate commit. Differential Revision: http://reviews.llvm.org/D14554 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@253622 91177308-0d34-0410-b5e6-96231b3b80d8
