Greg Clayton 4570d3eba0 Massive test suite cleanup to stop everyone from manually having to compute "mydir" inside each test case.
This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.

Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

Greg Clayton 7fdf9ef15d Added a new Host class: ReadWriteLock
This abstracts read/write locks on the current host system. It is currently backed by pthread_rwlock_t objects so it should work on all unix systems.

We also need a way to control multi-threaded access to the process through the public API when it is running. For example it isn't a good idea to try and get stack frames while the process is running. To implement this, the lldb_private::Process class now contains a ReadWriteLock member variable named m_run_lock which is used to control the public process state. The public process state represents the state of the process as the client knows it. The private is used to control the actual current process state. So the public state of the process can be stopped, yet the private state can be running when evaluating an expression for example. 

Adding the read/write lock where readers are clients that want the process to stay stopped, and writers are clients that run the process, allows us to accurately control multi-threaded access to the process.

Switched the SBThread and SBFrame over to us shared pointers to the ExecutionContextRef class instead of making their own class to track this. This fixed an issue with assigning on SBFrame to another and will also centralize the code that tracks weak references to execution context objects into one location.

Johnny Chen 5ccbccfce0 Add a @benchmarks_test decorator for test method we want to categorize as benchmarks test.
The test driver now takes an option "+b" which enables to run just the benchmarks tests.
By default, tests decorated with the @benchmarks_test decorator do not get run.

Add an example benchmarks test directory which contains nothing for the time being,
just to demonstrate the @benchmarks_test concept.

For example,

$ ./dotest.py -v benchmarks

...

$ ./dotest.py -v +b benchmarks

Also mark some Python API tests which are missing the @python_api_test decorator.

Johnny Chen 0d4f6dd01e o lldbutil.py:
For the print_stacktrace(thread, string_buffer = False) function, if we have debug info
  for a frame function, let's also emit the args for the current function.

o TestFrameUtils.py:

  Add stronger assertTrue for frame0's args.

o TestPrintStackTraces.py:

  Launch the inferior with ["abc", "xyz"] and expect '(int)argc=3' in the stack traces, since
  by design the inferior is built with debug info.

Johnny Chen 5a0bee7c5f The extra burden for the Python API test case to assign its process object to self.process
in order to have its process cleaned up (terminated) upon tearDown is gone for good.
Let's simplify a bunch of Python API test cases.

Johnny Chen 112f5696fb Add truth value testing to those lldb Python objects with the IsValid() method definitions.
object.__nonzero__(self) is called to implement truth value testing and the built-in operation bool(),
via a simple delegation to self.IsValid().

Change tests under python_api/lldbutil to utilize this mechanism.

Johnny Chen ad7372c538 Add two utility functions:
o get_parent_frame(frame)
    o get_args_as_string(frame)

to lldbutil.py and create TestFrameUtils.py to exercise the utils.
Plus re-arrange the test/python_api/lldbutil to have three directories
for testing iteration, process stack traces, and the just added frame utils.
