           Summary: Crash in codegen with inline asm using "+S" and "+D"
                    operands

C code at http://llvm.org/bugs/attachment.cgi?id=1397. llvm-gcc and clang
compile this code to different asm statements, leading to different asserts.

With llvm-gcc, this triggers a "matching constraints for memory operands unimp"
assertion in SelectionDAGISel.  Despite this, I'm pretty sure this is unrelated
to Bug 1133.

clang, on the other hand, triggers a "Unknown constraint type" in
SelectionDAGISel.
