CheckTailCallReturnConstraints is missing a check on the
incomming chain of the RETURN node. The incomming chain must
be the outgoing chain of the CALL node. This causes the
backend to identify tail calls that are not tail calls.

Fixed in <http://llvm.org/viewvc/llvm-project?view=rev&revision=73387>.
