[Reland] Detect against invalid variant index for LibStdC++ std::variant data formatters (#69614)
This is relanding of https://github.com/llvm/llvm-project/pull/69253.
`TestTemplatePackArgs.py` is passing now.

https://github.com/llvm/llvm-project/pull/68012/files added new data
formatters for LibStdC++ std::variant.

However, this formatter can crash if std::variant's index field has
invalid value (exceeds the number of template arguments).
This can happen if the current IP stops at a place std::variant is not
initialized yet.

This patch fixes the crash by ensuring the index is a valid value and
fix GetNthTemplateArgument() to make sure it is not crashing.

Fix std::variant test failure on certain buildbot (#68139)
https://github.com/llvm/llvm-project/pull/68012 works on my CentOS Linux
and Macbook but seems to fail for certain build bots. The error log
complains "No Value" check failure for `std::variant` but not very
actionable without a reproduce.

To unblock the build bots, I am commenting out the "No Value" checks.

487ab39a50 [lldb][test] Remove tests relying on deprecated std::char_traits specializations
(motivated by test failures after D157058)

With D157058 the base template for `std::char_traits` was removed from
libc++. Quoting the release notes:

```
The base template for ``std::char_traits`` has been removed. If you are using
``std::char_traits`` with types other than ``char``, ``wchar_t``, ``char8_t``,
``char16_t``, ``char32_t`` or a custom character type for which you
specialized ``std::char_traits``, your code will no longer work.
```

This patch simply removes all such instantiations to make sure the
tests that run against the latest libc++ version pass.

One could try testing the existence of this base template from within
the test source files but this doesn't seem like something we want
support.

[NFC][Py Reformat] Reformat python files in lldb
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.

44bb442fd5 [lldb][DataFormatter] Add dereference support to libstdcpp std::shared_ptr formatter
This mimicks the implementation of the libstdcpp std::unique_ptr
formatter.

This has been attempted several years ago in
`0789722d85cf1f1fdbe2ffb2245ea0ba034a9f94` but was reverted in
`e7dd3972094c2f2fb42dc9d4d5344e54a431e2ce`.

The difference to the original patch is that we now maintain
a `$$dereference$$` member and we only store weak pointers
to the other children inside the synthetic frontend. This is
what the libc++ formatters do to prevent the recursion mentioned
in the revert commit.

4076664228 [lldb][test] Replace use of p with expression (NFC)
In API tests, replace use of the `p` alias with the `expression` command.

To avoid conflating tests of the alias with tests of the expression command,
this patch canonicalizes to the use `expression`.

This reverts commit 859ebca744e634dcc89a2294ffa41574f947bd62.
The change contained many unrelated changes and e.g. restored

This reverts commit 640beb38e7710b939b3cfb3f4c54accc694b1d30.

That commit caused performance degradtion in Quicksilver test QS:sGPU and a functional test failure in (rocPRIM rocprim.device_segmented_radix_sort).
Reverting until we have a better solution to s_cselect_b64 codegen cleanup

99451b4453 [lldb][test] Remove symlink for API tests.
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.
