Backport of JDK-8272568 with follow-up fixes (see Commits).

This PR contains the following commits:
1. [JDK-8272586](https://bugs.openjdk.org/browse/JDK-8272586): emit abstract machine code in hs-err logs
This is the main part. Almost clean. Code move had to be done manually because `JavaThread::cast(t)` was introduced after JDK17. (JDK17 uses `t->as_Java_thread()`.)
2. [JDK-8275031](https://bugs.openjdk.org/browse/JDK-8275031): runtime/ErrorHandling/MachCodeFramesInErrorFile.java fails when hsdis is present
Small fix. Clean.
3. [JDK-8277102](https://bugs.openjdk.org/browse/JDK-8277102): Dubious PrintCompilation output
Basically reverts the timestamp change. Clean.

I'm planning to backport the other follow-up changes separately:
1. [JDK-8274986](https://bugs.openjdk.org/browse/JDK-8274986): max code printed in hs-err logs should be configurable
Clean but replacement of `JavaThread::cast` is needed.
2. [JDK-8283056](https://bugs.openjdk.org/browse/JDK-8283056): show abstract machine code in hs-err for all VM crashes
Clean.

The feature greatly helps analyzing VM crashes.
