[lldb] Add diagnostics
Around this time last year, I said on the mailing list [1] that I wanted
to to transform the reproducers into something that resembles a
sysdiagnose on Apple platforms: a collection of files containing a
variety of information to help diagnose bugs or troubleshoot issues.

This patch adds that framework. Based on lessons learned from the
reproducers, I've intentionally tried to keep it small and simple.
Different parts of LLDB can register callbacks (this is necessary for
layering purposes) that will get called when the diagnostics should be
generated.
