facilitate session recording.  This happens inside an instance method where the
test instance is well known.

pass in a 'sender' arg to the buildDefault(), buildDsym(), buildDwarf(), and
cleanup() functions.  The sender arg will be the test instance itself (i.e.,
an instance of TestBase).  This is so that the relevant command execution can be
recorded in the TestBase.session object if sender is available.

The lldbtest.system() command has been modified to pop the 'sender' arg out of
the keyword arguments dictionary and use it as the test instance to facilitate
seesion recordings.  An example is in test/types/AbstractBase.py:

    def generic_type_tester(self, atoms, quotedDisplay=False):
        """Test that variables with basic types are displayed correctly."""

        # First, capture the golden output emitted by the oracle, i.e., the
        # series of printf statements.
        go = system("./a.out", sender=self)

There are cases when sender is None.  This is the case when the @classmethod is
involved in the use of these APIs.  When this happens, there is no recording
into a session object, but printing on the sys.stderr is still honored if the
trace flag is ON.

An example is in test/settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm -f output.txt"])
        system(["/bin/sh", "-c", "rm -f stdout.txt"])

Changed all of our synthesized "___clang" functions, types and variables
that get used in expressions over to have a prefix of "$_lldb". Now when we
do name lookups we can easily switch off of the first '$' character to know
if we should look through only our internal (when first char is '$') stuff,
or when we should look through program variables, functions and types.

Converted all of the clang expression code over to using "const ConstString&" 
values for names instead of "const char *" since there were many places that
were converting the "const char *" names into ConstString names and them
throwing them away. We now avoid making a lot of ConstString conversions and
benefit from the quick comparisons in a few extra spots.

Converted a lot of code from LLVM coding conventions into LLDB coding 
conventions.
