`CodeGen/Generic/ForceStackAlign.ll` `FAIL`s on SPARC like this:

  LLVM ERROR: Function "g" required stack re-alignment, but LLVM couldn't handle it (probably because it has a dynamic alloca).

According to the comments in `llvm/lib/Target/Sparc/SparcFrameLowering.cpp` (`SparcFrameLowering::emitPrologue`) and `SparcRegisterInfo.cpp` (`SparcRegisterInfo::canRealignStack`) this isn't going to change any time soon, so this patch `XFAIL`s the test.

Tested on `sparcv9-sun-solaris2.11`.
