Incomplete concurrency runtime tooling and visibility

6/10 Medium

Concurrency runtime analytics tools are inadequate, especially for Linux environments. LLDB lacks support for async task stack backtraces, task creation/running/sleeping information, and task locals inspection, limiting debugging and profiling capabilities.

Concurrency runtime analytics tools could be richer, especially for Tasks - while we have some of the tooling in Instruments, it would be fantastic to also have support for accessing similar task information (async task stack backtraces etc, for creation/running/sleeping) in LLDB (especially import on Linux that lacks Instruments...)
