edc77353da [lldb/crashlog] Improve exception reporting for interactive mode
This patch improve exception reporting when loading a crash report in a
scripted process. Now, we parse the `exception` dictionary from the
crash report use it the create a higher fidelity `MachException` stop info.

This patch also updates the test to reflect that change.

a633c5e11b [lldb/crashlog] Add '-t|--target' option to interactive mode
This patch introduces a new flag for the interactive crashlog mode, that
allow the user to specify, which target to use to create the scripted
process.

This can be very useful when lldb already have few targets created:
Instead of taking the first one (zeroth index), we will use that flag to
create a new target. If the user didn't provide a target path, we will rely
on the symbolicator to create a targer.If that fails and there are already
some targets loaded in lldb, we use the first one.

4c2fb2e551 [lldb/crashlog] Fix interactive crashlog test
This patch should fix the interactive crashlog test by checking in the
binary as a yaml to regeneate the binary with the addresses and offsets
when running the test.

12301d616f [lldb/crashlog] Parse thread fields and pass it to crashlog scripted process
Previously, the ScriptedThread used the thread index as the thread id.

This patch parses the crashlog json to extract the actual thread "id" value,
and passes this information to the Crashlog ScriptedProcess blueprint,
to create a higher fidelity ScriptedThreaad.

It also updates the blueprint to show the thread name and thread queue.

Finally, this patch updates the interactive crashlog test to reflect
these changes.

0a65112cf7 [lldb/crashlog] Create artificial frames for non-crashed scripted threads
This patch pipes down the `-a|--load-all` crashlog command option to the
Scripted Process initializer to load all the images used by crashed
process instead of only loading the images related to the crashed
thread.

This allows us to recreate artificial frames also for the non-crashed
scripted threads.

7c54ffdc6c [lldb/crashlog] Add CrashLogScriptedProcess & remove interactive mode
This patch introduces a new type of ScriptedProcess: CrashLogScriptedProcess.
It takes advantage of lldb's crashlog parsers and Scripted Processes to
reconstruct a static debugging session with symbolicated stackframes, instead
of just dumping out everything in the user's terminal.

The crashlog command also has an interactive mode that only provide a
very limited experience. This is why this patch removes all the logic
for this interactive mode and creates CrashLogScriptedProcess instead.

This will fetch and load all the libraries that were used by the crashed
thread and re-create all the frames artificially.
