[PATCH] D89938: [DAG][PowerPC] Do not overwrite flags in `getNodeIfExists` without passing `Flags` argument

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

I think getNodeIfExists() should have the same semantics with respect to flags as getNode().

Maybe we can add a new helper "doesNodeExist()" which just returns a boolean, and doesn't mess with the flags?
