Med Ismail Bennani 72e25978f9 [lldb/API] Add SetDataWithOwnership method to SBData
This patch introduces a new method to SBData: SetDataWithOwnership.

Instead of referencing the pointer to the data, this method copies the
data buffer into lldb's heap memory.

This can prevent having the underlying DataExtractor object point to
freed/garbage-collected memory.

Levon Ter-Grigoryan f23b829a26 Fixed use of -o and -k in LLDB under Windows when statically compiled with vcruntime.
Right now if the LLDB is compiled under the windows with static vcruntime library, the -o and -k commands will not work.

The problem is that the LLDB create FILE* in lldb.exe and pass it to liblldb.dll which is an object from CRT.
Since the CRT is statically linked each of these module has its own copy of the CRT with it's own global state and the LLDB should not share CRT objects between them.

In this change I moved the logic of creating FILE* out of commands stream from Driver class to SBDebugger.
To do this I added new method: SBError SBDebugger::SetInputStream(SBStream &stream)

Command to build the LLDB:
cmake -G Ninja -DLLVM_ENABLE_PROJECTS="clang;lldb;libcxx"  -DLLVM_USE_CRT_RELEASE="MT" -DLLVM_USE_CRT_MINSIZEREL="MT" -DLLVM_USE_CRT_RELWITHDEBINFO="MT" -DP
YTHON_HOME:FILEPATH=C:/Python38 -DCMAKE_C_COMPILER:STRING=cl.exe -DCMAKE_CXX_COMPILER:STRING=cl.exe ../llvm

Command which will fail:
lldb.exe -o help

Pavel Labath 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.

Tatyana Krasnukha 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.

Raphael Isemann 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.
