A MachO userspace corefile may contain LC_THREAD commands which specify thread exception state. For arm64* only (for now), report a human-readable version of this state as the thread stop reason, instead of 'SIGSTOP'. As a follow-up, similar functionality can be implemented for x86 cores by translating the trapno/err exception registers. rdar://82898146 Differential Revision: https://reviews.llvm.org/D109795 (cherry picked from commit 3b14d80)
