33d74170a3 [LLDB] Modifying expression code in MakeLoadImageUtilityFunction to be more consistent
MakeLoadImageUtilityFunction() is not using extern "C" for external C functions
and it is not using eLanguageTypeC_plus_plus. So I am modifying it to be consistent.

[lldb] Migrate condition evaluation failure to ReportError
Migrate to using ReportError to report a failure to evaluate a
watchpoint condition. I had already done so for the parallel code for
breakpoints.

In the process, I noticed that I accidentally regressed the error
reporting for breakpoint conditions by dropping the call to
GetDescription. This patch rectifies that and adds a test.

Because the call to GetDescription expects a Stream*, I also switches
from using a raw_string_ostream to a StreamString for both breakpoints
and watchpoints.

Commit 3251ba2d0fcf ("[Attr] Fix a btf_type_tag AST generation")

[lldb] Report debugger diagnostics as events
Report warnings and errors through events instead of printing directly
the to the debugger's error stream. By using events, IDEs such as Xcode
can report these issues in the UI instead of having them show up in the
debugger console.

The new diagnostic events are handled by the default event loop. If a
diagnostic is reported while nobody is listening for the new event
types, it is printed directly to the debugger's error stream.

Re-land "[lldb] Synchronize output through the IOHandler"
Add synchronization to the IOHandler to prevent multiple threads from
writing concurrently to the output or error stream.

A scenario where this could happen is when a thread (the default event
thread for example) is using the debugger's asynchronous stream. We

[lldb] Fix platform selection on Apple Silicon (again)
This patch is another attempt to fix platform selection on Apple
Silicon. It partially undoes D117340 which tried to fix the issue by
always instantiating a remote-ios platform for "iPhone and iPad Apps on
Apple Silicon Macs".

While the previous patch worked for attaching, it broke launching and
everything else that expects the remote platform to be connected. I made
an attempt to work around that, but quickly found out that there were
just too may places that had this assumption baked in.

This patch takes a different approach and reverts back to marking the
host platform compatible with iOS triples. This brings us back to the
original situation where platform selection was broken for remote iOS
debugging on Apple Silicon. To fix that, we now look at the process'
host architecture to differentiate between iOS binaries running remotely
and iOS binaries running locally.

I tested the following scenarios, which now all uses the desired
platform:

  - Launching an iOS binary on macOS: uses the host platform
  - Attaching to an iOS binary on macOS: uses the host platform
  - Attaching to a remote iOS binary: uses the remote-ios platform

ffb9429b6f [lldb] Remove the global platform list
This patch moves the platform creation and selection logic into the
per-debugger platform lists. I've tried to keep functional changes to a
minimum -- the main (only) observable difference in this change is that
APIs, which select a platform by name (e.g.,
Debugger::SetCurrentPlatform) will not automatically pick up a platform
associated with another debugger (or no debugger at all).

I've also added several tests for this functionality -- one of the
pleasant consequences of the debugger isolation is that it is now
possible to test the platform selection and creation logic.

This is a product of the discussion at
