Subject: [PATCH] stream: prevent object map change in ReadableState

ReadableState has the resumeScheduled property that helps determine if
a stream should be resumed. It was not assigned in the constructor.
When stream.resume is called on a readable stream that is not flowing,
it is set to true. This changes the property map of the ReadableState
which can cause a deopt in onEofChunk and needMoreData.
