The `llvm-gcc` front-end has been EOL'd at least since 2011 (based on
some `git` archeology). And Clang/LLVM has been removing references to
it ever since.
This patch removes the remaining references to it from LLDB. One benefit
of this is that it will allow us to remove the code checking for
`DW_AT_decl_file_attributes_are_invalid` and
`Supports_DW_AT_APPLE_objc_complete_type`.
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.

With this patch member-function pointers are formatted using
`CXXFunctionPointerSummaryProvider`.
This turns,
```
(lldb) v pointer_to_member_func
(void (Foo::*)()) ::pointer_to_member_func = 0x00000000000000000000000100003f94
```
into
```
(lldb) v pointer_to_member_func
(void (Foo::*)()) ::pointer_to_member_func = 0x00000000000000000000000100003f94 (a.out`Foo::member_func() at main.cpp:3)

Before this patch, LLDB used to format pointers to members, such as,
```
void (Foo::*pointer_to_member_func)() = &Foo::member_func;
```
as `eFormatBytes`. E.g.,
```
(lldb) v pointer_to_member_func
(void (Foo::*)()) $1 = 94 3f 00 00 01 00 00 00 00 00 00 00 00 00 00 00
```
This patch makes sure we format pointers to member functions the same
way we do regular function pointers.
After this patch we format member pointers as:
```
(lldb) v pointer_to_member_func
(void (Foo::*)()) ::pointer_to_member_func = 0x00000000000000000000000100003f94

This patch adds a test for formatting of member function pointers.
This was split from https://reviews.llvm.org/D145242, which caused
this test case to fail on Windows buildbots.
I split this out in order to make sure that this indeed works on Windows
without the D145242 patch.

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`.

I'm trying to add a test which tests that the same substr occurs twice in a row, but it matches even if only one of the substr occurs.
This found a bug in concurrent_base.py.

Based on post-commit review discussion on
2bd84938470bf2e337801faafb8a67710f46429d with Richard Smith.
Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).
This was originally committed in 277623f4d5a672d707390e2c3eaf30a9eb4b075c
Reverted in f9ad1d1c775a8e264bebc15d75e0c6e5c20eefc7 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).
Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:

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.
