[jdk17u-dev] RFR: 8320001: javac crashes while adding type annotations to the return type of a constructor [v3]

[Liam Miller-Cushon]

> This is a backport of [JDK-8320001: javac crashes while adding type annotations to the return type of a constructor](https://bugs.openjdk.org/browse/JDK-8320001), which fixes a regression introduced by [JDK-8225377: type annotations are not visible to javac plugins across compilation boundaries](https://bugs.openjdk.org/browse/JDK-8225377).
> 
> I resolved a trivial merge conflict due to a change on an adjacent line.
> 
> Testing: included test fails without the fix, and passes with it applied
