Fix or suppress upcoming JSCompiler type errors

See for the original errors being fixed. A JSCompiler change will improve type information in some cases, which uncovers these new errors.

If you've received a CL with suppressions or casts, you are warmly encouraged to properly fix it later on (or if the fix is simple, please suggest an edit).
