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.

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).

Summary:
There was a bug on LLDB VSCode where there was the following behavior:
//Code
```
struct foo {
int bar:
};
...
foo my_foo = {10};
```
Trying to auto-complete my_foo.b with my_foo.bar resulted instead with my_foo.my_foo.bar
This diff fixes this bug and adds some tests to check correct behavior.
It also fixes the same bug using the arrow operator (->) when user manually requests completions.

Summary:
Currently we crash in Clang's CodeGen when we call functions with covariant return types with this assert:
```
Assertion failed: (DD && "queried property of class with no definition"), function data, file clang/include/clang/AST/DeclCXX.h, line 433.
```
when calling `clang::CXXRecordDecl::isDerivedFrom` from the `ItaniumVTableBuilder`.
Clang seems to assume that the underlying record decls of covariant return types are already completed.
This is true during a normal Clang invocation as there the type checker will complete both decls when
checking if the overloaded function is valid (i.e., the return types are covariant).
When we minimally import our AST into the expression in LLDB we don't do this type checking (which
would complete the record decls) and we end up trying to access the invalid record decls from CodeGen
which makes us trigger the assert.
This patch just completes the underlying types of ptr/ref return types of virtual function so that the
underlying records are complete and we behave as Clang expects us to do.

We want that the *.py names for the tests have unique names but
the current ones are sometimes very simple (e.g., "TestUniquePtr.py")
and could collide with unrelated tests. This just gives all these
tests a "FromStdModule" suffix to make these collisions less likely.
BreakpointSites know they're backed by hardware based on whether the
"hardware index" is set. This does not appear the to be done for

The test was printing a char[3] variable without a terminating nul. The
memory after that variable (an unnamed bitfield) was not initialized. If
the memory happened to be nonzero, the summary provider for the variable
would run off into the next field.
This is probably not the right behavior (it should stop at the end of
the array), but this is not the purpose of this test. I have filed
pr44649 for this bug, and fixed the test to not depend on this behavior.
We ran into an assert when debugging clang and performing an expression on a class derived from DeclContext. The assert was indicating we were getting the offsets wrong for RecordDeclBitfields. We were getting both the size and offset of unnamed bit-field members wrong. We could fix this case with a quick change but as I extended the test suite to include more combinations we kept finding more cases that were being handled incorrectly. A fix that handled all the new cases as well as the cases already covered required a refactor of the existing technique.

calls to commonly un-overridden methods into a function that checks whether
the method is overridden anywhere and if not directly dispatches to the
NSObject implementation.
That means if you do override any of these methods, "step-in" will not step
into your code, since we hit the wrapper function, which has no debug info,
and immediately step out again.
Add code to recognize these functions as "trampolines" and a thread plan that
will get us from the function to the user code, if overridden.

Summary:
This commit renames ClangASTContext to TypeSystemClang to better reflect what this class is actually supposed to do
(implement the TypeSystem interface for Clang). It also gets rid of the very confusing situation that we have both a
`clang::ASTContext` and a `ClangASTContext` in clang (which sometimes causes Clang people to think I'm fiddling
with Clang's ASTContext when I'm actually just doing LLDB work).
I also have plans to potentially have multiple clang::ASTContext instances associated with one ClangASTContext so
the ASTContext naming will then become even more confusing to people.
