fix a bug in findNonImmUse (used by IsLegalToFold) where nodes with
no id's would cause early exit allowing IsLegalToFold to return true instead of false, producing a cyclic dag. This was striking the new isel because it isn't using SelectNodeTo yet, which theoretically is just an optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96972 91177308-0d34-0410-b5e6-96231b3b80d8
