ed2853d2c8 Reland [lldb] Fix TestThreadStepOut.py after "Flush local value map on every instruction"
The original patch got reverted as a dependency of cf1c774d6a .
That patch got relanded so it's also necessary to reland this patch.

Original summary:

After cf1c774d6a, Clang seems to generate code
that is more similar to icc/Clang, so we can use the same line numbers for
all compilers in this test.

77f0ea4b5b [lldb] [test] Fix continue_to_breakpoint() args in TestThreadStepOut
The test is skipped/xfailing on all platforms, so it seems that the API
got out of sync.  Fix that so it returns to a 'proper' failure
on FreeBSD.

615f63e149 Revert "[FastISel] Flush local value map on ever instruction" and dependent patches
This reverts commit cf1c774d6a.

This change caused several regressions in the gdb test suite - at least
a sample of which was due to line zero instructions making breakpoints
un-lined. I think they're worth investigating/understanding more (&
possibly addressing) before moving forward with this change.

Revert "[FastISel] NFC: Clean up unnecessary bookkeeping"
This reverts commit 3fd39d3694.

Revert "[FastISel] NFC: Remove obsolete -fast-isel-sink-local-values option"

f21e704d4a [lldb] [Process/NetBSD] Copy the recent improvements from FreeBSD
Copy the recent improvements from the FreeBSDRemote plugin, notably:

- moving event reporting setup into SetupTrace() helper

- adding more debug info into SIGTRAP handling

- handling user-generated (and unknown) SIGTRAP events

- adding missing error handling to the generic signal handler

- fixing attaching to processes

- switching watchpoint helpers to use llvm::Error

- minor style and formatting changes

This fixes a number of tests, mostly related to fixed attaching.

2c2eb5e670 [lldb] Enable FreeBSDRemote plugin by default and update test status
The new FreeBSDRemote plugin has reached feature parity on i386
and amd64 targets.  Use it by default on these architectures, while
allowing the use of the legacy plugin via FREEBSD_LEGACY_PLUGIN envvar.

Revisit the method of switching plugins.  Apparently, the return value
of PlatformFreeBSD::CanDebugProcess() is what really decides whether
the legacy or the new plugin is used.

Update the test status.  Reenable the tests that were previously
disabled on FreeBSD and do not cause hangs or are irrelevant to FreeBSD.
Mark all tests that fail reliably as expectedFailure.  For now, tests
that are flaky (i.e. produce unstable results) are left enabled
and cause unpredictable test failures.

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).

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.

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

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
