They don't require that the memory return address be restored prior to
function exit, so there's no guarantee the value is correct. It's better
to return nothing that something that's not accurate.

This diff is adding the capping_size determination for the list and forward list, to limit the number of children to be displayed. Also it modifies and unifies tests for libcxx and libstdcpp list data formatter.

This adds a basic SB API for creating and stopping traces.
Note: This doesn't add any APIs for inspecting individual instructions. That'd be a more complicated change and it might be better to enhande the dump functionality to output the data in binary format. I'll leave that for a later diff.
This also enhances the existing tests so that they test the same flow using both the command interface and the SB API.
I also did some cleanup of legacy code.

This patch adds an `SBTarget::IsLoaded(const SBModule&) const` endpoint
to lldb's Scripting Bridge API. As the name suggests, it will allow the
user to know if the module is loaded in a specific target.

This translates most of the old ASCII art in our documentation to the
equivalent in restructured text (which the new version of the LLDB docs
is using).
This patch exposes the Target::CreateBreakpoint overload with the
boolean argument to move to the neareast code to the SBAPI.
This is useful when creating column breakpoints to restrict lldb's
resolution to the pointed source location, preventing it to go to the next
line.

This patch moves the SB API method GetExtendedCrashInformation from
SBTarget to SBProcess since it only makes sense to call this method on a
sane process which might not be the case on a SBTarget object.
It also addresses some feedbacks received after landing the first patch
for the 'crash-info' feature.

Currently, in macOS, when a process crashes, lldb halts inside the
implementation disassembly without yielding any useful information.
The only way to get more information is to detach from the process, then wait
for ReportCrash to generate a report, find the report, then see what error
message was included in it. Instead of waiting for this to happen, lldb could
locate the error_string and make it available to the user.
This patch addresses this issue by enabling the user to fetch extended
crash information for crashed processes using `process status --verbose`.
Depending on the platform, this will try to gather different crash information
into an structured data dictionnary. This dictionnary is generic and extensible,
as it contains an array for each different type of crash information.
On Darwin Platforms, lldb will iterate over each of the target's images,
extract their `__crash_info` section and generated a StructuredData::Array
containing, in each entry, the module spec, its UUID, the crash messages
and the abort cause. The array will be inserted into the platform's
`m_extended_crash_info` dictionnary and `FetchExtendedCrashInformation` will
return its JSON representation like this:
```
{
"crash-info annotations": [
{
"abort-cause": 0,
"image": "/usr/lib/system/libsystem_malloc.dylib",
"message": "main(76483,0x1000cedc0) malloc: *** error for object 0x1003040a0: pointer being freed was not allocated",
"message2": "",
"uuid": "5747D0C9-900D-3306-8D70-1E2EA4B7E821"
},
...
],
...
}
```
This crash information can also be fetched using the SB API or lldb-rpc protocol
using SBTarget::GetExtendedCrashInformation().

All the code required to generate the language bindings for Python and
Lua lives under scripts, even though the majority of this code aren't
scripts at all, and surrounded by scripts that are totally unrelated.
I've reorganized these files and moved everything related to the
language bindings into a new top-level directory named bindings. This
makes the corresponding files self contained and much more discoverable.
