[jdk8u-dev] RFR: 8313626: C2 crash due to unexpected exception control flow

[Sergey Bylokhov]

Hi all,

This pull request contains a backport of commit [f8203cb2](https://github.com/openjdk/jdk/commit/f8203cb272e6136b784e5c43a500f6a0bfb19c8b) from the [openjdk/jdk](https://git.openjdk.org/jdk) repository.

The commit being backported was authored by Tobias Holenstein on 23 Aug 2023 and was reviewed by Tobias Hartmann and Christian Hagedorn.

The patch is mostly clean. The jdk8u still widely uses "#ifndef PRODUCT/#endif" in the context. The usage of that macro was deleted by the next patch in jdk9: https://github.com/openjdk/jdk/commit/6896030b9620e89546527fbfd19369366b5ad3d5#diff-2797e2c78bff502b5d98cab2383791529d267cfd3099575872c756fcd715e143L858

- No new issues were found by the tier1 and tier2 tests. 
- The new test passes before and after the patch, same as for jdk11u, see:

Thanks!
