JDK-8307549 - AsyncGetCallTrace crashes on Mac M1 after JDK-8294160
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.

> 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.
