Though we do not make a promise to process GWT.create() of entry point
types before any other GWT.create() calls, it was easy to restore this
behavior in incremental, so I went ahead and did it (
https://gwt-review.googlesource.com/#/c/10410/).
You should probably find a way not to depend on this in the future, as it
is not promised and may change again.
