619e2e095f [lldb] Convert assertTrue(a == b) to assertEqual(a, b)
Convert `assertTrue(a == b)` to `assertEqual(a, b)` to produce better failure messages.

These were mostly done via regex search & replace, with some manual fixes.

This reverts commit 754ab803b8.

As pointed out in https://reviews.llvm.org/D95761, this patch could lead to
having the wrong execution context in some situations (thanks Jim!).

D92164 is addressing the same issue and will replace this patch, so I'll
revert this one.

754ab803b8 [lldb] Use current execution context in SBDebugger
Use `GetSelectedExecutionContext()` instead of
`GetCommandInterpreter().GetExecutionContext()` in
`SBDebugger::GetInternalVariableValue/SBDebugger::SetInternalVariable`. The
execution context in the command interpreter might be empty, if no commands has
been executed yet (it is updated only when handling commands or completions --
e.g.
https://github.com/llvm/llvm-project/blob/main/lldb/source/Interpreter/CommandInterpreter.cpp#L1855).

122a4ebde3 Revert "[lldb] Make CommandInterpreter's execution context the same as debugger's one."
This reverts commit a01b26fb51, because it
breaks the "finish" command in some way -- the command does not
terminate after it steps out, but continues running the target. The
exact blast radius is not clear, but it at least affects the usage of
the "finish" command in TestGuiBasicDebug.py. The error is *not*
gui-related, as the same issue can be reproduced by running the same
steps outside of the gui.

There is some kind of a race going on, as the test fails only 20% of the
time on the buildbot.

a01b26fb51 [lldb] Make CommandInterpreter's execution context the same as debugger's one.
Currently, the interpreter's context is not updated until a command is executed.
This has resulted in the behavior of SB-interface functions and some commands
depends on previous user actions. The interpreter's context can stay uninitialized,
point to a currently selected target, or point to one of previously selected targets.

This patch removes any usages of CommandInterpreter::UpdateExecutionContext.
CommandInterpreter::HandleCommand* functions still may override context temporarily,
but now they always restore it before exiting. CommandInterpreter saves overriden
contexts to the stack, that makes nesting commands possible.

Added test reproduces one of the issues. Without this fix, the last assertion fails
because interpreter's execution context is empty until running "target list", so,
the value of the global property was updated instead of process's local instance.

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.

30d5590d17 [lldb] Fix TestTargetAPI.py on Apple simulators
This test checks that the output of `SBTarget.GetDescription()` contains the
substrings `'a.out', 'Target', 'Module', 'Breakpoint'` in that order. This test
is currently failing on Apple simulators as apparently 'Module' can't be found
in the output after 'Target".

The reason for that is that the actual output of `SBTarget.GetDescription()` looks like this:
```
Target
  Module /build/path/lldb-test-build.noindex/python_api/target/TestTargetAPI.test_get_description_dwarf/a.out
0x7ff2b6d3f990:     ObjectFileMachO64, file = /build/path/lldb-test-build.noindex/python_api/target/TestTargetAPI.test_get_description
[...]
0x7ff307150000:   BreakpointList with 0 Breakpoints:
<LLDB module output repeats for each loaded module>
```

Clearly the string order should be `'Target', 'Module', 'a.out', 'Breakpoint'`.
However, LLDB is also a bunch of system shared libraries (libxpc.dylib,
libobjc.A.dylib, etc.) when *not* running against a simulator, we end up
unintentionally finding the `'Target', 'Module', 'Breakpoint'` substrings in the
trailing descriptions of the system modules. When running against a simulator we
however don't load shared system libraries.

This patch just moves the substrings in the correct order to make this test pass
without having any shared library modules in the description output.

bb4efab9a4 [lldb] Use SBProcess::Continue instead of 'run' command in TestTargetAPI.py
This test is flaky on Green Dragon as it often fails when the process state
is "Invalid" in the assert:
    self.assertEqual(process.GetState(), lldb.eStateExited)
It seems this is related to just doing "run" which apparently invalidates
the Target's process in case it's still running and needs to be restarted.
Just doing 'continue' on the process (and ignoring the error in case it already
finished) prevents that and makes this consistently pass for me.

9cdd68e7c1 Recommit "[lldb/API] Overwrite variables with SBLaunchInfo::SetEnvironment(append=true)"
The patch was reverted 27d52cd86a because of failures in
TestWeakSymbols.py. These have now been addressed in D83552.

The original commit message was:
This function was documented to overwrite entries with D76111, which was
adding a couple of similar functions. However, this function (unlike the
functions added in that patch) was/is not actually overwriting variables
-- any pre-existing variables would get ignored.

This behavior does not seem to be intentional. In fact, before the refactor in
D41359, this function could introduce duplicate entries, which could
have very surprising effects both inside lldb and on other applications
(some applications would take the first value, some the second one; in
lldb, attempting to unset a variable could make the second variable
become active, etc.).

Overwriting seems to be the most reasonable behavior here, so change the
code to match documentation.

35674976f0 [lldb/Test] Introduce "assertSuccess"
Summary:
A lot of our tests do 'self.assertTrue(error.Success()'. The problem
with that is that when this fails, it produces a completely useless
error message (False is not True) and the most important piece of
information -- the actual error message -- is completely hidden.

Sometimes we mitigate that by including the error message in the "msg"
argument, but this has two additional problems:
- as the msg argument is evaluated unconditionally, one needs to be
  careful to not trigger an exception when the operation was actually
  successful.
- it requires more typing, which means we often don't do it

assertSuccess solves these problems by taking the entire SBError object
as an argument. If the operation was unsuccessful, it can format a
reasonable error message itself. The function still accepts a "msg"
argument, which can include any additional context, but this context now
does not need to include the error message.

To demonstrate usage, I replace a number of existing assertTrue
assertions with the new function. As this process is not easily
automatable, I have just manually updated a representative sample. In
some cases, I did not update the code to use assertSuccess, but I went
for even higher-level assertion apis (runCmd, expect_expr), as these are
even shorter, and can produce even better failure messages.
