This reverts commit r200561. This calling convention was an attempt to match the MSVC C++ ABI for methods that return structures by value. This solution didn't scale, because it would have required splitting every CC available on Windows into two: one for methods and one for free functions. Now that we can put sret on the second arg (r208453), and Clang does that (r208458), revert this hack. llvm-svn: 208459
