the option to print the runtime-specific description has been modified in the frame variable, memory read and expression command.

All three commands now support a --object-description option, with a shortcut of -O (uppercase letter o)

This is a breaking change:
frame variable used --objc as the long option name
expression used -o as a shortcut
memory read uses --objd as the long option name

Hopefully, most users won't be affected by the change since people tend to access "expression --object-description" under the alias "po" which still works

The test suite has been tweaked accordingly.

Adding a validation callback mechanism to OptionValueString (such a feature might theoretically be added to the general OptionValue base class should the need arise)

"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.

Fix Test11588.py on Linux.  The test was failing because the synthetic type fields were resolving to int instead of long.  A similar change was made in r155144 to eliminate the type specification for an earlier check in this test, so it seemed appropriate here too.

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

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.
