[analyzer] Fix crash inside RangeConstraintManager.cpp introduced by …
f61a08b 
…D112621

It seems like `LHS` and `RHS` could be empty range sets.
This caused an assertion failure inside RangeConstraintManager.

I'm hoisting out the check from the function into the call-site.
This way we could assert that we only want to deal with non-empty range
sets.

[TSan] Avoid deadlock between ReportRace() and dlopen() interceptor
24e3102 
This change prevents rare deadlocks observed for specific macOS/iOS GUI
applications which issue many `dlopen()` calls from multiple different
threads at startup and where TSan finds and reports a race during
startup.  Providing a reliable test for this has been deemed infeasible.

Although I've only observed this deadlock on Apple platforms,
conceptually the cause is not confined to Apple code so the fix lives in
platform-independent code.

Deadlock scenario:
```
Thread 2                    | Thread 4
ReportRace()                |
Lock internal TSan mutexes  |
  &ctx->slot_mtx            |
                            | dlopen() interceptor
                            | OnLibraryLoaded()
                            | MemoryMappingLayout::DumpListOfModules()
                            | calls dyld API, which takes internal lock
                            | lock() interceptor
                            | TSan tries to take internal mutexes again
                            |   &ctx->slot_mtx
call into symbolizer        |
MemoryMappingLayout::DumpListOfModules()
calls dyld API, which hangs on trying to take lock
```
Resulting in:
* Thread 2 has internal TSan mutex, blocked on dyld lock
* Thread 4 has dyld lock, blocked on internal TSan mutex

The fix prevents this situation by not intercepting any of the calls
originating from `MemoryMappingLayout::DumpListOfModules()`.

[clang][clangd] Don't crash/assert on -gsplit-dwarf=single without ou…

The crash happens in clang::driver::tools::SplitDebugName when Output is
InputInfo::Nothing. It doesn't happen with standalone clang driver because
output is created in Driver::BuildJobsForActionNoCache.

Example backtrace:
```

[lldb] Return unimplemented error from ScriptedProcessInterface::Crea…
02ef12d 
…tePluginObject

After llvm/llvm-project#68052 this function changed from returning
a nullptr with `return {};` to returning Expected and hitting `llvm_unreachable` before it could
do so.

I gather that we're never supposed to call this function, but on Windows we actually do call
this function because `interpreter->CreateScriptedProcessInterface()` returns
`ScriptedProcessInterface` not `ScriptedProcessPythonInterface`. Likely because
`target_sp->GetDebugger().GetScriptInterpreter()` also does not return a Python related class.

The previously XFAILed test crashed with:

```

That might be a bug on the Windows side, or an artifact of how our build is setup,
but whatever it is, having `CreatePluginObject` return an error and
the caller check it, fixes the failing test.

The built lldb can run the script command to use Python, but I'm not sure if that means
anything.

Revert "[Coro] [async] Disable inlining in async coroutine splitting …
2e29c91 
…(#80904)"

This reverts commit b1ac052.

This commit breaks coroutine splitting for non-swift calling convention
functions. In this example:

```ll

target triple = "x86_64-unknown-linux-gnu"

@0 = internal constant { i32, i32 } { i32 trunc (i64 sub (i64 ptrtoint (ptr @craSH to i64), i64 ptrtoint (ptr getelementptr inbounds ({ i32, i32 }, ptr @0, i32 0, i32 1) to i64)) to i32), i32 64 }

define dso_local void @af_suspend_fn(ptr %0, i64 %1, ptr %2) #0 {

  %4 = getelementptr inbounds { ptr, { ptr, ptr }, i64, { ptr, i1 }, i64, i64 }, ptr poison, i32 0, i32 0
  %5 = call ptr @llvm.coro.async.resume()
  store ptr %5, ptr %4, align 8
  %6 = call { ptr, ptr, ptr } (i32, ptr, ptr, ...) @llvm.coro.suspend.async.sl_p0p0p0s(i32 0, ptr %5, ptr @ctxt_proj_fn, ptr @af_suspend_fn, ptr poison, i64 -1, ptr poison)
  ret void
}

define dso_local ptr @ctxt_proj_fn(ptr %0) #0 {

}

; Function Attrs: nomerge nounwind
