[Lldb-commits] [lldb] fallback to assembly when source code is not available (PR #136494)

Maybe I'm missing something, but I disagree with this change. We're talking about when you're stopped in a stack frame that has debug info (a file and line number), but the source file is unavailable, right.  There is a setting to control this behavior already -- `stop-disassembly-display`.  It defaults to `no-debuginfo`, but it can be `never`, `always`, `no-source`, or `no-debuginfo`.  

People who are debugging at a source level, generally, do not want to see assembly, and in fact will be confused if they are shown assembly.  We do not want to show assembly for a stack frame where we have a debug filename and line number, by default.  The user may not have set up the target.source-map to map lldb to the source file, and could be looking at it in another source window as they're stepping, or they may know roughly how many lines a method has as they step through it.  The assembly only adds distraction to them.

Am I misunderstanding what we're talking about here?
