[lldb-dap] Using an empty target instead of a dummy target. (#189734)

Removing the use of the dummy target and instead letting the debugger
instance create the target it needs.

[lldb] Disable TestTsan{CPP}GlobalLocation.py on Linux (#191018)

Skip `TestTsanGlobalLocation.py` and `TestTsanCPPGlobalLocation.py` on
Linux. The tests are failing on GreenDragon and at desk.

[flang][OpenACC] Support DO CONCURRENT locality specs inside ACC constructs (#190406)

- Lower DO CONCURRENT locality specs (REDUCE, LOCAL, LOCAL\_INIT) that
appear inside OpenACC compute constructs and combined directives.
- Previously, any locality spec on DO CONCURRENT inside ACC hit a `TODO`
and aborted. This resolves that limitation.
- Per OpenACC 2.17.2, DO CONCURRENT without a loop construct in a
kernels construct is treated as `loop auto`; in a parallel construct it
is treated as `loop independent`. Both cases are covered.

## Mapping

| Locality Spec | ACC Operation |
|---|---|
| `REDUCE(op:vars)` | `acc.reduction` with reduction recipe |
| `LOCAL(vars)` | `acc.private` with privatization recipe |
| `LOCAL_INIT(vars)` | `acc.firstprivate` with firstprivatization recipe
|
| `SHARED` / `DEFAULT(NONE)` | No-op (variables already accessible) |

[clang] Introduce scopes for arguments without destructors

The current way we mark argument lifetimes is overly conservative for
most programs. To improve the status quo, we can introduce a new scope
for the arguments when it is safe to do so. This applies to aggregate
types that do not have destructors, and Objective-C types that are not
managed by reference counting (ARC). These rules may be possible to
refine more, but this recaptures a significant amount of the cases where
temporary objects never have their storage reused in stack coloring.

Note: I used an LLM to help draft test changes and suggest the scoping
rules for Objective-C.
