Summary: Detect this crash in the signal handler and give a fatal error 
message  instead of making us chase down bugs that don't reproduce

This change also has more information for crash site from bug 

guarantee(cb->is_adapter_blob() || cb->is_method_handles_adapter_blob()) 
failed: exception happened outside interpreter, nmethods and vtable 
stubs (1) <https://jbs.oracle.com/bugs/browse/JDK-8007019>

There used to be two places that had the same message so they were 
qualified by (1) and (2).   The second one is gone.   Now this prints 
the blob and pc.

Tested with full vm.quick.testlist and the sets of jdi tests that failed 
with -client -Xcomp and specjvm98 that used to fail with this signal 
code.   I got one failure two days ago before this change but now it 
won't fail with my new message or at all.
