Fixing `test/langtools/tools/javac/diags/CheckExamples.java` (`test/langtools/tools/javac/diags/examples/PrimitivePatternMatching.java`) and `test/langtools/tools/javac/preview/PreviewAutoSuppress.java` tests.
Unfortunately, it is quite hard to make the tests work both with and without `-DDISABLE_PREVIEW_PATCHING=true` (could be done for `PreviewAutoSuppress.java`, but it is very hard to do sensible for `CheckExamples.java`), so given the future is `-DDISABLE_PREVIEW_PATCHING=true`, this change forces this option. (The practical impact of testing only this variant for these two tests is basically zero, I think. We have a different test that verifies all the combinations.) ------------- Commit messages: - Fixing test when running with -DDISABLE_PREVIEW_PATCHING=true (and forcing a run with this option).
