rG0a65112cf710: [lldb/crashlog] Create artificial frames for non-crashed scripted threads
Summary

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.

Can we cover this case in the existing test?

We need to make it multi-threaded. I'll do it.

LGTM. I think we've reached a point where the test binary has become complex enough that we should check it in instead of hoping that the offsets will match, but that's something that can/should be done in a separate patch.
