More cleanup to remove the CoreFoundation classes out of mainstream code (CFCMutableDictionary, CFCMutableArray, CFCString, etc). Now it is only used in the Results.cpp file for Apple builds only.

Much more cleanup on the performance testing infrastructure:
- Added new abtract Results class to keep CoreFoundation out of the tests. There are many subclasses for different settings:
Results::Result::Dictionary
Results::Result::Array
Results::Result::Unsigned
Results::Result::Double
Results::Result::String
- Gauge<T> can now write themselves out via a templatized write to results function:
template <class T>
Results::ResultSP GetResult (const char *description, T value);
- There are four specializations of this so far:
template <>
Results::ResultSP GetResult (const char *description, double value);
template <>
Results::ResultSP GetResult (const char *description, uint64_t value);
template <>
Results::ResultSP GetResult (const char *description, std::string value);
template <>
Results::ResultSP GetResult (const char *description, MemoryStats value);
- Don't emit the virtual memory reading from the task info call as it really doesn't mean much as it includes way too much (shared cache + other stuff we don't have control over)
- Fixed other test cases to build correctly and use the new classes

Code cleanup:
- don't use preprocessor macros
- use switch statements
- don't put anything in the lldb namespace, use "lldb_perf" namespace.
- Pass the action struct into each TestStep() for each step fill in
- Modify the ActionWanted class to have accessors to make the continue, next, finish, kill instead of using preproc macros

Initial checkin of a new project: LLDB Performance Testing Infrastructure
This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance
This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions
There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
<dict>
<key>fetch-frames</key>

<real>0.029676525769230768</real>
</dict>
</array>
</plist>
Areas for improvement:
- code cleanups (I will be out of the office for a couple days this coming week, but please keep ideas coming!)
- more metrics and test cases
- better error checking
This toolkit also comprises a simple event-loop-driven controller for LLDB, similar yet much simpler to what the Driver does to implement the lldb command-line tool.
