The Cocoa formatters now provide error messages for many of the common things-went-wrong situations. Previously they would say nothing or log failures to the Python console

llvm-svn: 152673

Changed several of the Cocoa formatters to match the output style that Xcode uses internally to provide summaries
This has been done for those summaries where the difference is only cosmetic (e.g. naming things as items instead of values, ...)
The LLDB output style has been preserved when it provides more information (e.g. telling the type as well as the value of an NSNumber)

Test cases have been updated to reflect the updated output style where necessary

Fixing a problem with the NSSet summary provider; plus, providing a further optimization to the whole Cocoa formatters infrastructure

 (a) the SystemParameters object is now passed around to the formatters; doing so enables the formatters to reuse computed values for things such as pointer-size and endianness
     instead of repeatedly computing these on their own
 (b) replacing the global ISA cache with a per-process one
 (c) providing a per-process types cache where each formatter can store the types it needs to operate, and be sure to find them the next time without recalculating them
     this also enables formatters to share types if they agree on a local naming convention
 (d) lazy fetching of data from Objective-C runtime data structures
     data is fetched as needed and we stop reading as soon as we determine that an ISA is actually garbage

fixed a few potential NULL-pointer derefs in ValueObject
we have a way to provide docstrings for properties we add to the SWIG layer - a few of these properties have a docstring already, more will come in future commits
added a new bunch of properties to SBData to make it more natural and Python-like to access the data they contain

(b) fixes and improvements to the formatters for NSDate and NSString
(c) adding an introspection formatter for NSCountedSet
(d) making the Objective-C formatters test cases pass on both 64 and 32 bit
    one of the test cases is marked as expected failure on i386 - support needs to be added to the LLDB core for it to pass

llvm-svn: 151826

1) solving a bug where, after Jim's fixes to stack frames, synthetic children were not recalculated when necessary, causing them to get out of sync with live data
2) providing an updated list of tagged pointers values for the objc_runtime module - hopefully this one is final
3) changing ValueObject::DumpValueObject to use an Options class instead of providing a bulky list of parameters to pass around
   this change had been laid out previously, but some clients of DumpValueObject() were still using the old prototype and some arguments
   were treated in a special way and passed in directly instead of through the Options class
4) providing new GetSummaryAsCString() and GetValueAsCString() calls in ValueObject that are passed a formatter object and a destination string
   and fill the string by formatting themselves using the formatter argument instead of the default for the current ValueObject
5) removing the option to have formats and summaries stick to a variable for the current stoppoint
   after some debate, we are going with non-sticky: if you say frame variable --format hex foo, the hex format will only be applied to the current command execution and not stick when redisplaying foo
   the other option would be full stickiness, which means that foo would be formatted as hex for its whole lifetime
   we are open to suggestions on what feels "natural" in this regard

 a) adds a Python summary provider for NSDate
 b) changes the initialization for ScriptInterpreter so that we are not passing a bulk of Python-specific function pointers around
 c) provides a new ScriptInterpreterObject class that allows for ref-count safe wrapping of scripting objects on the C++ side
 d) contains much needed performance improvements:
    1) the pointer to the Python function generating a scripted summary is now cached instead of looked up every time
    2) redundant memory reads in the Python ObjC runtime wrapper are eliminated
    3) summaries now use the m_summary_str in ValueObject to store their data instead of passing around ( == copying) an std::string object
 e) contains other minor fixes, such as adding descriptive error messages for some cases of summary generation failure

The formatter for NSString is an improved version of the one previously shipped as an example, the others are new in design and implementation.
A more robust and OO-compliant Objective-C runtime wrapper is provided for runtime versions 1 and 2 on 32 and 64 bit.
The formatters are contained in a category named "AppKit", which is not enabled at startup.
