"self" when those pointers are in registers.
Previously in this case the IRInterpreter would
handle them just as if the user had typed in
"$rdi", which isn't safe because $rdi is passed
in through the argument struct.
Now we correctly break out all three cases (i.e.,
normal variables in registers, $reg, and this/self),
and handle them in a way that's a little bit easier
to read and change.
This results in more accurate printing of "this" and
"self" pointers all around. I have strengthened the
optimized-code test case for Objective-C to ensure
that we catch regressions in this area reliably in
the future.

Fixed zero sized arrays to work correctly. This will only happen once we get a clang that emits correct debug info for zero sized arrays. For now I have marked the TestStructTypes.py as an expected failure.

- Removed the BitfieldMap class because it is unnecessary.
We now just track the most recently added field.
- Moved the code that calculates bitfield widths so it
can also be used to determine whether it's necessary
to insert anonymous fields.
- Simplified the anonymous field calculation code into
three cases (two of which are resolved identically).
- Beefed up the bitfield testcase.

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.
This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

- use lldb settings command instead of os.environ
- use dyldPath fixture variable instead of hardcoding LD_LIBRARY_PATH
- add tear-down hook to restore environment after testcase is run

- use lldb 'settings' command to help testcase find shared library
- pull up dyldPath variable from TestLoadUnload.py to fixture base class (applicable in multiple cases)

expressions that refer to ivars will not work because Clang
emits IR that refers to them to get the ivar offsets.
However, it is possible to search the runtime for these values.
I have added support for reading the relevant tables to the
Objective-C runtime, and extended ClangExpressionDeclMap to
query that information if and only if it doesn't find the symbols
in the binary.
Also added a testcase.

and silence the backtrace printout
In the process, refactor the Execute* commands in ScriptInterpreter to take an options object, and add a new setting to not mask out errors so that the callers can handle them directly
instead of having the default behavior

Changed all relevant test cases to verify that MightHaveChildren() works correctly for objects of interest
Added a bunch of convenience methods for test cases to use: target(), process(), thread() and frame() which mimic the lldb.X convenience variables
As a bonus, edited the documentation on the website to describe the new method available for synthetic children providers writers to implement!
That's all folks!

Temporarily disable the "out of scope" checking since it didn't work correctly, and was
not what people generally expected watchpoints to be doing.

Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar*
If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was
no trivial way for us to change the SP inside an SBValue on the fly
This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM)
As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython
Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases)
