e982b4f411 [lldb][test] Add tests for printing references to C-strings
Printing references to C-strings doesn't work properly at the moment. This patch provides coverage for those cases and should fail once the underlying issue gets fixed (see https://github.com/llvm/llvm-project/pull/174398).

[lldb][test] Rewrite TestStringPrinter.py in a non-inline API test style (#174385)
Motivation here is that I'm planning to add more test cases to this and
it's easier to read/maintain as an API test.

Drive-by:
* I also removed the `std::string` checks since those belong in the STL
formatter tests.

acf77bd2fd [lldb] Don't print *trailing* nuls in char arrays
Embedded nul characters are still printed, and they don't terminate the
string. See also D111634.

31c7165a2b [lldb] Remove summary for signed char *
It conflicts with the summary for BOOL * (aka signed char *). This
partially reverts D112709.

11dc235c7d [lldb] Fix matchers for char array formatters
They were being applied too narrowly (they didn't cover signed char *,
for instance), and too broadly (they covered SomeTemplate<char[6]>) at
the same time.

ca0ce99fc8 [lldb] Print embedded nuls in char arrays (PR44649)
When we know the bounds of the array, print any embedded nuls instead of
treating them as terminators. An exception to this rule is made for the
nul character at the very end of the string. We don't print that, as
otherwise 99% of the strings would end in \0. This way the strings
usually come out the same as how the user typed it into the compiler
(char foo[] = "with\0nuls"). It also matches how they come out in gdb.

This resolves a FIXME left from D111399, and leaves another FIXME for dealing
with nul characters in "escape-non-printables=false" mode. In this mode the
characters cause the entire summary string to be terminated prematurely.

8093c2ea57 [lldb] Make char[N] formatters respect the end of the array (PR44649)
I believe this is a more natural behavior, and it also matches what gdb
does.

fdea9a4ec9 [lldb] Remove license headers from all test source files
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:
    lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
    lldb-shell :: Reproducer/TestGDBRemoteRepro.test
    lldb-shell :: Reproducer/TestMultipleTargets.test
    lldb-shell :: Reproducer/TestReuseDirectory.test
    lldb-shell :: ExecControl/StopHook/stop-hook-threads.test
    lldb-shell :: ExecControl/StopHook/stop-hook.test
    lldb-api :: lang/objc/exceptions/TestObjCExceptions.py

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.
