The compiler decides not to report compiler error while doing recovery on deferred types - this fix looks into the speculative types of a deferred type and if all the speculative types are erroneous, then use a recovery type as the target type, which later on in the pipeline will imply reporting errors if any. Adds test. Ran GHA Sanity Checks, local Tier 1 and 2, and new `test/langtools/tools/javac/recovery/CrashDueToUnreportedError.java` tests. Patch is clean.
