3b43f00629 [lldb] Check if thread was suspended during previous stop added.
Encountered the following situation: Let we started thread T1 and it hit
breakpoint on B1 location. We suspended T1 and continued the process.
Then we started thread T2 which hit for example the same location B1.
This time in a breakpoint callback we decided not to stop returning
false.

Expected result: process continues (as if T2 did not hit breakpoint) its
workflow with T1 still suspended. Actual result: process do stops (as if
T2 callback returned true).

Solution: We need invalidate StopInfo for threads that was previously
suspended just because something that is already inactive can not be the
reason of stop. Thread::GetPrivateStopInfo() may be appropriate place to
do it, because it gets called (through Thread::GetStopInfo()) every time
before process reports stop and user gets chance to change
m_resume_state again i.e if we see m_resume_state == eStateSuspended
it definitely means it was set during previous stop and it also means
this thread can not be stopped again (cos' it was frozen during
previous stop).

a976a7fcae Disable this test for Windows.
The printf expression crashes with the message:

Attempted to dereference an invalid pointer

Someone who knows more about Windows should suggest how to fix this.

f4d4273265 Add a test for preserving state on the non-expr thread across expression evaluation.
There may be another test that tests this but I couldn't find one.

5238b80058 [lldb/Reproducers] Skip or fix the remaining tests.
After this patch all remaining tests should pass on macOS when replayed
from a reproducer.

053b0634ea [lldb] Increase timeout in TestExitDuringExpression
200 microseconds is not enough time for any expression to execute
reliably. On linux, calling pthread_exit can result in call to dlopen,
which cannot complete in that time, particularly when running under a
debugger.

On linux, this test failed all the time, on macos, about two thirds of
runs were failing.  This patch increases the timeout to 100ms, which is
enough to get it passing reliably on linux, though I wouldn't be
surprised if an even bigger timeout would be needed for remote test
runs.

1583766ed2 This very simple .c file is failing on the Debian bot wit the error
undefined reference to pthread_create

I skipped the test till I can figure out why this didn't build.

56de738d18 [lldb-server] Reset stop reason of all threads when resuming
Summary:
This patch makes the stop reason reset logic similar to MacOS' debugserver, where exceptions are reset for all threads when resuming process for stepping or continuing (see [[ 96f3ea0d21/lldb/tools/debugserver/source/MacOSX/MachThreadList.cpp (L433) | MachThreadList::ProcessWillResume ]] and [[ 96f3ea0d21/lldb/tools/debugserver/source/MacOSX/MachThread.cpp (L363) | MachThread::ThreadWillResume ]]).

Resetting stop reasons on resume fixes problems where LLDB spuriously reports SIGTRAP signal stop reason for deleted breakpoints (both internal and public) and where  LLDB stops on an internal breakpoint while stepping over while a breakpoint is hit in another thread. See [[ https://bugs.llvm.org/show_bug.cgi?id=45642 | PR45642 ]] for details.

a31130f6fc [lldb][testsuite] Create a SBDebugger instance for each test
Some tests set settings and don't clean them up, this leads to side effects in other tests.
The patch removes a global debugger instance with a per-test debugger to avoid such effects.

From what I see, lldb.DBG was needed to determine the platform before a test is run,
lldb.selected_platform is used for this purpose now. Though, this required adding a new function
to the SBPlatform interface.

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.
