[PATCH] D27304: [PATCH] [Sema][X86] Don't allow floating-point return types when SSE is disabled

The logic to compute whether a calling convention uses SSE registers does exist in clang/lib/CodeGen/TargetInfo.cpp, so it might be possible to reuse that... but I'm not sure that's better than just detecting it in the backend.
