This required some minor API to be added to these types to avoid needing temp files. Also, I've used initializer lists in the tests, as MSVC 2013 claims to support them. I'll redo this without them if the bots complain. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229455 91177308-0d34-0410-b5e6-96231b3b80d8
