We have a Python script that needs to locate coredump path during
debugging so that we can retrieve certain metadata files associated with
it. Currently, there is no API for this.

This patch adds a new `SBProcess::GetCoreFile()` to retrieve target dump
file spec used for dump debugging. Note: this is different from the main
executable module spec. To achieve this, the patch hoists m_core_file
into PostMortemProcess for sharing.

 [lldb] [Process/FreeBSDKernel] Support finding all processes 2022-01-06T20:53:28+00:00 Michał Górny mgorny@moritz.systems 2021-12-22T07:45:16+00:00 9b1d27b2fa727a3a6f53a803d75beed50a1be999 Include the complete list of threads of all running processes in the FreeBSDKernel plugin. This makes it possible to inspect the states (including partial register dumps from PCB) of all kernel and userspace threads at the time of crash, or at the time of reading /dev/mem first.

[lldb] Introduce a FreeBSDKernel plugin for vmcores 2021-12-14T21:07:20+00:00 Michał Górny mgorny@moritz.systems 2021-12-01T22:04:59+00:00 9c7fbc3f9b05b3249468ef6aeacaf71841b5cfe3 Introduce a FreeBSDKernel plugin that provides the ability to read FreeBSD kernel core dumps. The plugin utilizes libfbsdvmcore to provide support for both "full memory dump" and minidump formats across variety of architectures supported by FreeBSD. It provides the ability to read kernel memory, as well as the crashed thread status with registers on arm64, i386 and x86_64. Differential Revision: https://reviews.llvm.org/D114911

I have failed to make the new tests conditional to the presence of libfbsdvmcore.
