Partial backport of analyzer async/await fixes to Java.
Backport of r43613, r43537, r43446, r43427, r43424, r43418, r43403,
r43361 to the Java-based analyzer. The backport is partial in that
the TypeProvider was not modified to include Future and Stream types
(this would have required substantial additional effort), and
consequently not all static warnings are correctly produced. However,
all NonErrorResolverTest cases were successfully backported and pass,
meaning that the Java-based analyzer shouldn't produce false positive
warnings for async/await code anymore.
