performing Objective-C instance variable lookup.
Previously, it only completed the derived class
that was the beginning of the search. Now, as
it walks up the superclass chain looking for the
ivar, it completes each superclass in turn.
Also added a testcase covering this issue.

LLDB (python bindings) Crashing in lldb::SBDebugger::DeleteTarget(lldb::SBTarget&)
Need to check the validity of (SBTarget&)target passed to SBDebugger::DeleteTarget()

Switch from GetReturnValue, which was hardly ever used, to GetReturnValueObject
which is much more convenient.
Return the "return value object" as a persistent variable if requested.

parser has hitherto been an implementation waiting
for a use. I have now tied the '-o' option for
the expression command -- which indicates that the
result is an Objective-C object and needs to be
printed -- to the ExpressionParser, which
communicates the desired type to Clang.
Now, if the result of an expression is determined
by an Objective-C method call for which there is
no type information, that result is implicitly
cast to id if and only if the -o option is passed
to the expression command. (Otherwise if there
is no explicit cast Clang will issue an error.
This behavior is identical to what happened before
r146756.)
Also added a testcase for -o enabled and disabled.

"id" from being found by the parser as an
externally-defined type. Before, "id" would
sometimes make it through if it was defined in
a namespace, but this sometimes caused
confusion, for example when it conflicted with
std::locale::id.

valobj.AddressOf() returns None when an address is expected in a SyntheticChildrenProvider
Patch from Enrico Granata:
The problem was that the frozen object created by the expression parser was a copy of the contents of the StgClosure, rather than a pointer to it. Thus, the expression parser was correctly computing the result of the arithmetic&cast operation along with its address, but only saving it in the live object. This meant that the frozen copy acted as an address-less variable, hence the problem.
The fix attached to this email lets the expression parser store the "live address" in the frozen copy of the address when the object is built without a valid address of its own.
Doing so, along with delegating ValueObjectConstResult to calculate its own address when necessary, solves the issue. I have also added a new test case to check for regressions in this area, and checked that existing test cases pass correctly.

we handle Objective-C method calls. Currently,
LLDB treats the result of an Objective-C method
as unknown if the type information doesn't have
the method's signature. Now Clang can cast the
result to id if it isn't explicitly cast.
I also added a test case for this, as well as a
fix for a type import problem that this feature
exposed.

Instead of getting the location of the variable and converting the hex string to an int, just use
val.AddressOf().GetValueAsUnsigned() to compute the address of the memory region to read from.

lldb::SBValue::CreateValueFromAddress does not verify SBType::GetPointerType succeeds
SBValue::CreateValueFromAddress() should check the validity of type and its derived pointer type
before using it. Add a test case.

clients to disassemble a series of raw bytes as
demonstrated by a new testcase.
In the future, this API will also allow clients
to provide a callback that adds comments for
addresses in the disassembly.
I also modified the SWIG harness to ensure that
Python ByteArrays work as well as strings as
sources of raw data.

LLDBSwigPythonCallCommand crashes when a command script returns an object
Add more robustness to LLDBSwigPythonCallCommand. It should check whether the returned Python object
is a string, and only assign it as the error msg when the check holds.
Also add a regression test.

There were two problems associated with this radar:
1. "settings show target.source-map" failed to show the source-map after, for example,
"settings set target.source-map /Volumes/data/lldb/svn/trunk/test/source-manager /Volumes/data/lldb/svn/trunk/test/source-manager/hidden"
has been executed to set the source-map.
2. "list -n main" failed to display the source of the main() function after we properly set the source-map.
The first was fixed by adding the missing functionality to TargetInstanceSettings::GetInstanceSettingsValue (Target.cpp)
and updating the support files PathMappingList.h/.cpp; the second by modifying SourceManager.cpp to fix several places
with incorrect logic.
Also added a test case test_move_and_then_display_source() to TestSourceManager.py, which moves main.c to hidden/main.c,
sets target.source-map to perform the directory mapping, and then verifies that "list -n main" can still show the main()
function.

translation unit has a interface for a class "Bar" that contains hidden ivars
in the implementation and we make sure we can see these hidden ivars. We also
test the case where we stop in translation unit that contains the
implementation first. So the test runs two tests:
1 - run and stop where we have an interface, run to main and print and make
sure we find the hidden ivar
2 - run and stop where we have an implementation, run to main and print and make
sure we find the hidden ivar
