version, and clang will say it supports the flag even if the linker
can't use its output.
The compiler actually has code to know whether the linker version is
right, and sets it to the default if the stars align.
So I'm going to just test whether whatever is the default method for the
compiler and linker works.
On Darwin, clang added a new objc class method dispatch, turned on by
the flag: `-fobjc-msgsend-class-selector-stubs`. These stubs are like
the accelerated stubs added previously for method selectors. This patch
adds support for stepping through them.
I had previously handled the method stubs by figuring out the object ->
class and then used the selector encoded in the stub name. But that
depended on all the stubs setting the object into arg1 before calling
the stub, which not all the stubs do anymore. Since all the stubs do
some work and then call objc_msgSend, instead of trying to predict what
the stub is going to do, I just let it run to the objc_msgSend and then
figure out how to go from there - at that point arg1 and arg2 are
correctly set, so I can use the regular objc_msgSend trampoline for
that.
That change meant I was no longer using the "find the implementation"
method that was passing in the selector string that we pulled from the
stub name, so this patch also removes that.
This uses [teyit](https://pypi.org/project/teyit/) to modernize asserts,
as recommended by the [unittest release
notes](https://docs.python.org/3.12/whatsnew/3.12.html#id3).
For example, `assertTrue(a == b)` is replaced with `assertEqual(a, b)`.
This produces better error messages, e.g. `error: unexpectedly found 1
and 2 to be different` instead of `error: False`.
This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

Convert `assertTrue(a == b)` to `assertEqual(a, b)` to produce better failure messages.
These were mostly done via regex search & replace, with some manual fixes.

Replace the plethora of ObjC-implied 'skipUnlessDarwin' decorators
with marking tests as 'objc' category (whenever missing), and skip all
ObjC tests on non-Darwin platforms. I have used '.categories' file
wherever it was present already or all (>1) tests were relying on ObjC,
and explicit add_test_categories() where there was only one test.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
