[jdk17u-dev] RFR: 8275233: Incorrect line number reported in exception stack trace thrown from a lambda expression [v4]

[Alexey Pavlyutkin]

> Hi! Here is backport of [JDK-8275233](https://bugs.openjdk.org/browse/JDK-8275233) that fixes incorrect `javac -g` flag processing. The issue was introduced by [JDK-8200301](https://bugs.openjdk.org/browse/JDK-8200301). It prevents proper debug info generation for labmdas, in particular it causes wrong line numbers in stack trace upon throwing an exception from a labmda fucntion.
> 
> The original patch applied cleanly
> 
> Verification (amd64/20.04LTS): test/langtools/tools/javac/lambda/deduplication/DeduplicationDebugInfo.java (new test)
> Regression (amd64/20.04LTS): test/langtools
