Currently, LLDB assumes all minidumps will have unique sections. This is intuitive because almost all of the minidump sections are themselves lists. Exceptions including Signals are unique in that they are all individual sections with their own directory. This means LLDB fails to load minidumps with multiple exceptions due to them not being unique. This behavior is erroneous and this PR introduces support for an arbitrary number of exception streams. Additionally, stop info was calculated only for a single thread before, and now we properly support mapping exceptions to threads. ~~This PR is starting in DRAFT because implementing testing is still required.~~
