Subject: [PATCH] Fix/suppress upcoming JSCompiler build errors

Upstreaming cl/236195240 from the jscompiler team.

These errors come from the compiler incorrectly overriding JSDoc on a declaration with its right-hand-side. In some cases the JSDoc should not have been there; in other cases the JSDoc was correct and this reveals an error elsewhere.
