[lldb] Fix CommandInterpreter::GetExecutionContext (#199922)

Following up Jonas's comment in #198949, this patch changes the function
to not ignore the override context in the adopt_dummy_target=false case.

However, I don't implement Jonas's suggestion exactly either. Instead of
"bypassing" the override context if it contains the dummy target, this
patch returns an empty context instead. I think this makes more sense,
as the intention of the user may very well have been to run the command
in the context of the dummy target. The test suite has no opinion either
way, but this is sufficient to fix the regression that #198949 was
trying to fix.

I also delete the test added in that PR, as the tests in this patch
cover more cases, and the test has the potential of interfering with
another process/test running on the same system.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
