- memory delta and time for: target create
- memory delta and time for: setting breakpoint at main by name
- time to launch and hit bp at main
- overall memory of target create + bp main + run to main
- ovarall time of target create + bp main + run to main

to in INADDR_LOOPBACK mode by default ("localhost only")
instead of INADDR_ANY ("accept connections from any system").
Add a new command line argument to debugserver, --open-connection
or -H which will enable the previous behavior. It would be used
if you were doing two-system debugging, with lldb running on one
system and debugserver running on the other. But it is a less
common workflow and should not be the default.

- 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

This is especially useful to take measurements that span multiple test steps, or where you need to have different operations fall under the same measurement
An example of use is in the formatters perf test case

- TestCase.m_thread is now filled in with the first thread that has a valid
stop reason. This eliminates the need for the SelectMyThread() functions.
- The first thread that stops for a reason is also set as the selected thread
in the process in case any command line commands are run.
- Changed launch over to take a SBLaunchInfo parameter so that the launch
function doesn't keep getting new arguments as they are needed.
- TestCase::Setup() and TestCase::Launch(SBLaunchInfo) now return bool to
indicate success of setup and launch.
- ActionWanted::Next(SBThread) was renamed to ActionWanted::StepOver(SBThread)
- ActionWanted::Finish(SBThread) was renamed to ActionWanted::StepOut(SBThread)

Fixed a crasher in the SourceManager where it wasn't checking the m_target member variable for NULL.
In doing this fix, I hardened this class to have weak pointers to the debugger and target in case they do go away. I also changed SBSourceManager to hold onto weak pointers to the debugger and target so they don't keep objects alive by holding a strong reference to them.

- 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

Added logging that will show up in the system console when we try to resume a process that is already running, or has an unexpected state.

Drop the old f registers from debugserver's register list. Add the
NEON 128-bit q registers to debugserver, support reading and writing.
Add the new contains / invalidates mappings for the s, d, and q
registers so lldb will know what registers overlay what other registers.
Change the default format of s and d registers to be floating point
instead of hex. Remove some UTF-8 hyphen chars in comments in the ARM
register number definition headers.

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">

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.

Make it configurable what to profile.
For Mac, we don't use the dirty page size yet and hence there is no need to gather that. This should be way better in not draining the battery since we are operating between 0% to 0.1% on the Mac after this change.
