Revert r135217, which wasn't the correct fix for PR10358. With this patch, we actually move the state-machine for the value set backwards one step. This can pretty easily lead to infinite loops where we continually try to propagate a bit, succeed for one iteration, but then back up because we find an uninitialized use. A reduced test case from PR10379 is included. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135359 91177308-0d34-0410-b5e6-96231b3b80d8
