Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.

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.

We now have a virtual-functions test and a multiple-inheritance test that
are testing the same functionality (and more) using the newer test functions which
we have in LLDB these days. These tests should also be less flaky and
less dependent on other unrelated LLDB functionality.
This actually tests all the different situations in which we can call virtual
functions. This removes also all skipIfs as the first skipIf for Linux is
apparently fixed and the second skipIf was just failing due to the constructor
call (which should be its own test and not be tested here).

Reid found a bug in removing Listeners from a BroadcasterManager:
https://reviews.llvm.org/D74010
The bug didn't affect the case where there was only one Listener
signed up for a BroadcasterManager, which was all the extant test
case tests. The driver also only uses one listener (the debugger)
for everything, so neither the test nor anything you do with lldb
command line would have triggered the bug.
This adds a couple more tests using more listeners, and adding and
removing them in a different way, which triggers a separate code path.
Summary:
This creates a separate LLDB_TEST_SRC var to match the existing LLDB_TEST var. LLDB_TEST points to the test framework, LLDB_TEST_SRC points to the tests themselves.
The var points to the same place, but a future patch will move the tree + update var.

By clearing the recognizers before starting the test, we ensure that the
recognizers that get initialized when lldb starts won't alter the

To my knowledge we don't actually use or need these rules. And if we need them then

When a thread stops, this checks depending on the platform if the top frame is
an abort stack frame. If so, it looks for an assert stack frame in the upper
frames and set it as the most relavant frame when found.
To do so, the StackFrameRecognizer class holds a "Most Relevant Frame" and a
"cooked" stop reason description. When the thread is about to stop, it checks
if the current frame is recognized, and if so, it fetches the recognized frame's
attributes and applies them.

This patch has a couple of outstanding issues. The test is not python3
compatible, and it also seems to fail with python2 (at least under some
circumstances) due to an overambitious assertion.

Pass the correct library directory from CMake to dotest.py when linking

Changing the date2 to an timezone independent value broke the test as the data formatters
uses the current time zone for the summary (so changing it to a time zone independent value
would again break the test in some time zones). We anyway just care about this for date2
which will be printed in a timezone-independent summary.
Summary:
This test creates its dates with `NSDate dateWithNaturalLanguageString` which is deprecated and uses the current time zone of the machine to
interpret the input string. This causes that the created NSDate has a different value depending on the locale of the machine
and we hardcoded the value for California's time zone (PST) but the data formatter gives out the GMT value as a string.
This just replaces the use with the timezone-independent dateWithTimeIntervalSince1970 (which we also use in the rest of the test)
to make this pass independently of the time zone of the machine running the test.

Summary:
Currently having a typedef for ObjC types is breaking member access in LLDB:
```
typedef NSString Str;
NSString *s; s.length; // OK
Str *s; s.length; // Causes: member reference base type 'Str *' (aka 'NSString *') is not a structure or union
```
This works for NSString as there the type building from `NSString` -> `NSString *` will correctly
build a ObjCObjectPointerType (which is necessary to make member access with a dot possible),
but for the typedef the `Str` -> `Str *` conversion will produce an incorrect PointerType. The reason
for this is that our check in TypeSystemClang::GetPointerType is not desugaring the base type,
which causes that `Str` is not recognised as a type to a `ObjCInterface` as the check only sees the
typedef sugar that was put around it. This causes that we fall back to constructing a PointerType
instead which does not allow member access with the dot operator.
This patch just changes the check to look at the desugared type instead.

Re-landing this now that (hopefully) all the failures this caused on the
bots have been addressed.
This patch changes the behavior of the substrs argument to self.expect.
Currently, the elements of substrs are unordered and as long as the
string appears in the output, the assertion passes.
We can be more precise by requiring that the substrings be ordered in
the way they appear. My hope is that this will make it harder to
accidentally pass a check because a string appears out of order.

Value::GetValueByteSize() reports the size of a Value as the size of its
underlying CompilerType. However, a host buffer that backs a Value may
be smaller than GetValueByteSize().
This situation arises when the host is only able to partially evaluate a
Value, e.g. because the expression contains DW_OP_piece.
The cleanest fix I've found to this problem is Greg's suggestion, which
is to resize the Value if (after evaluating an expression) it's found to
be too small. I've tried several alternatives which all (in one way or
the other) tried to teach the Value/ValueObjectChild system not to read
past the end of a host buffer, but this was flaky and impractical as it
isn't easy to figure out the host buffer's size (Value::GetScalar() can
point to somewhere /inside/ a host buffer, but you need to walk up the
ValueObject hierarchy to try and find its size).
This fixes an ASan error in lldb seen when debugging a clang binary.
I've added a regression test in test/functionalities/optimized_code. The
point of that test is not specifically to check that DW_OP_piece is
handled a particular way, but rather to check that lldb doesn't crash on
an input that it used to crash on.
Testing: check-lldb, and running the added tests using a sanitized lldb
--
Thanks to Jim for pointing out that an earlier version of this patch,
which simply changed the definition of Value::GetValueByteSize(), would
interact poorly with the ValueObject machinery.
Thanks also to Pavel who suggested a neat way to test this change
(which, incidentally, caught another ASan issue still present in the
original version of this patch).
