c131dfefe2 [lldb] Disable auto fix-its when evaluating expressions in the test suite
Summary:
Currently the test suite runs with enabled automatically applied Clang fix-its for expressions.
This is causing that sometimes incorrect expressions in tests are still evaluated even though they
are actually incorrect. Let's disable this feature in the test suite so that we know when expressions
are wrong and leave the fix-it testing to the dedicated tests for that feature.

Also updates the `lang/cpp/operators/` test as it seems Clang needs the `struct` keywords
before C and would otherwise fail without fixits.

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

53eece04bd [lldb][NFC] Modernize test setup code in several lang/cpp tests
All these tests can just call lldbutil.run_to_source_breakpoint
instead of reimplementing it.

1b2deb9ae0 [lldb] Remove Windows X-fail for TestCPPAuto and TestStepTarget
TestCPPAuto was only failing on windows due to the std::string
copying (which was not related at all to 'auto' functionality).

TestStepTarget is now also passing but that seems more that we
now have by accident the right behavior in Windows. I'll remove
the x-fail just to make the bot green again.

a3093bfb3e [lldb] Let TestCppConstructors pass without fix-it intervention
This should use -> instead of '.', but the fix-it functionality of
the expression evaluator saved us here. Let's use the proper syntax
in the first place as we don't want to test fix-its here.

2bab1738f3 [lldb] Make TestFormatters.py not rely on working constructor calls
All calls to operator new in this test fail for me with:
```
expression --show-types -- *(new foo(47))`
Error output:
error: Execution was interrupted, reason: internal c++ exception breakpoint(-6)..
The process has been returned to the state before expression evaluation.
```

As calling operator new isn't the idea of this test, this patch moves that
logic to the binary with some new_* utility functions and explicitly tests
this logic in the constructor test (where we can isolate the failures and
skip them on Linux).

cfb29e4a54 [lldb] Fix some tests failing with gmodules after change to stdlib.h
Commit 82b47b2978405f802a33b00d046e6f18ef6a47be changes the way the stdlib.h
header is structured which seems to cause strange lookup failures in the modules
build. This updates a few failing tests so that they pass with the new
behavior of stdlib.h.

b3a0c4d7dc [lldb] Replace assertTrue(a == b, "msg") with assertEquals(a, b, "msg") in the test suite
Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.

This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys

def sanitize_line(line):
  if line.strip().startswith("self.assertTrue(") and " == " in line:
    line = line.replace("self.assertTrue(", "self.assertEquals(")
    line = line.replace(" == ", ", ", 1)
  if line.strip().startswith("self.assertTrue(") and " != " in line:
    line = line.replace("self.assertTrue(", "self.assertNotEqual(")
    line = line.replace(" != ", ", ", 1)
  return line

for a in sys.argv[1:]:
  with open(a, "r") as f:
    lines = f.readlines()
  with open(a, "w") as f:
    for line in lines:
      f.write(sanitize_line(line))
```

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.
