Description
Try to recover and output meaningful information in more situations, such as:
- when a pointer is in Method metadata memory range, but the memory is not committed
- when we call a bad address

When calling a bad address, we usually don't get a meaningful stack backtrace, but in many situations we can if we know where to find the caller information.

Thanks [~dlong] for confirming. I created JDK-8343343 to add support on more platforms. For bsd_x86 we probably can just copy the coding that was used in this change.

[~mbaesken], I think it would indeed be useful on those other platforms. In hindsight, I could have pinged and gotten help from the port maintainers on the other platforms when working on the PR.

Hi [~dlong] , [~dholmes] this change adjusted frame os::fetch_frame_from_context(const void* ucVoid) on linux arrch64, linux x86_64, windows x86_64 to use os::fetch_frame_from_context(uc).pc(); . Is there a reason why it was done only on those platforms and not on others (like bsd_x86, linux-ppc64 etc.) ? Is there no need for it on those platforms or was it just not done because they were seen not so important (or you could not test those) ?

> Low risk, touches code only used in error situation. It turns out this code is used not only for error reporting, but also for profiling. This change has broken AsyncGetCallTrace on Mac M1. I'll submit an issue shortly.

Fix request [17u] I backport this for parity with 17.0.7-oracle. Low risk, touches code only used in error situation. I had to resolve. SAP nightly testing passed.
