Keno Fischer 1dbe2693fc Do not insert a tail call when returning multiple values on X86 ... Summary: This fixes http://llvm.org/bugs/show_bug.cgi?id=19530. The problem is that X86ISelLowering erroneously thought the third call was eligible for tail call elimination. It would have been if it's return value was actually the one returned by the calling function, but here that is not the case and additional values are being returned. Test Plan: Test case from the original bug report is included.
