[lldb/crashlog] Add support for Last Exception Backtrace
This patch adds support to the "Last Exception Backtrace" to the `crashlog` command. This metadata is homologous to the "Application Specific Backtrace", however the format is closer to a regular stack frame. Since the thread that "contains" the "Last Exception Backtrace" doesn't really exist, this information is displayed when requesting an extended backtrace of the crashed thread, similarly to the "Application Specific Backtrace". To achieve that, this patch includes some refactors and fixes to the existing "Application Specific Backtrace" handling. rdar://113046509 Differential Revision: https://reviews.llvm.org/D157851 Signed-off-by: Med Ismail Bennani <[email protected]>
