Added a stress-tester for LLDB's disassembler.
Right now it only works on Mac OS X, but other
platforms would just need to add their own
implementation of AddLLDBToSysPathOn*().

The stress-tester has two modes:

Used with --bytes N --random, the stress-tester
generates random instructions of length N and
runs them through the disassembler.  This is
suitable for architectures like Intel where it
is combinatorially infeasible to run through the
entire space of possible instructions.

Used with --bytes N and no arguments (or --start
S --stride T), the stress-tester tests the
disassembler with a monotonically increasing
sequence of instructions.

The --start and --stride arguments are intended
for use in multiprocessing environments.  Give
each core an ID from 0 .. T-1, pass the ID in as
the --start, and use T as the stride, and you
can launch one copy of the stress-tester on each
core you have available.

Add a new option to the test driver, -N dsym or -N dwarf, in order to exclude tests decorated with
either @dsym_test or @dwarf_test to be executed during the testsuite run.  There are still lots of
Test*.py files which have not been decorated with the new decorator.

An example:

# From TestMyFirstWatchpoint.py ->
class HelloWatchpointTestCase(TestBase):

    mydir = os.path.join("functionalities", "watchpoint", "hello_watchpoint")

    @dsym_test
    def test_hello_watchpoint_with_dsym_using_watchpoint_set(self):
        """Test a simple sequence of watchpoint creation and watchpoint hit."""
        self.buildDsym(dictionary=self.d)
        self.setTearDownCleanup(dictionary=self.d)
        self.hello_watchpoint()

    @dwarf_test
    def test_hello_watchpoint_with_dwarf_using_watchpoint_set(self):
        """Test a simple sequence of watchpoint creation and watchpoint hit."""
        self.buildDwarf(dictionary=self.d)
        self.setTearDownCleanup(dictionary=self.d)
        self.hello_watchpoint()
