Fix PR6497, a bug where we'd fold a load into an addc node which has a flag. That flag in turn was used by an already-selected adde which turned into an ADC32ri8 which used a selected load which was chained to the load we folded. This flag use caused us to form a cycle. Fix this by not ignoring chains in IsLegalToFold even in cases where the isel thinks it can. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97791 91177308-0d34-0410-b5e6-96231b3b80d8
