siginfo: si_signo: 4 (SIGILL), si_code: 1 (ILL_ILLOPC), si_addr: 0x00007fff676ab63c

I'm starting this bug off in hotspot/compiler ONLY because the
last sighting of SIGILL in _os_unfair_lock_recursive_abort is
associated with this hotspot/compiler bug:

    JDK-8259508 CtwOfSpecJvm.java fails on MacOSX with _os_unfair_lock_recursive_abort in TDescriptorSource::CopySplicedDescriptorForName

JDK-8259508 was closed as "External" because of something
to do with the test machine where the failure occurred, but I
couldn't quite nail down what was wrong with the machine.
