Leo Li 11ba81c3df [ConstantHoisting] Remove dupliate logic in constant hoisting ... Summary: As metioned in https://reviews.llvm.org/D34576, checkings in `collectConstantCandidates` can be replaced by using `llvm::canReplaceOperandWithVariable`. The only special case is that `collectConstantCandidates` return false for all `IntrinsicInst` but it is safe for us to collect constant candidates from `IntrinsicInst`.
