Previously, CMake was invoking the test runner and not specifying
what architecture to use when building test executables. The
Makefiles for the test executables then had logic to choose x64
by default. This doesn't work on Windows because the test compiler
would then try to link against the 64-bit MSVCRT and not find them
since only the 32-bit MSVCRT was in the path.
This patch addresses this by figuring out, at CMake time, whether
or not you are building LLDB with a 64 or 32-bit toolchain. Then,
it explicitly passes this value to the test runner, causing the
test runner to build tests whose architecture matches that of LLDB
itself. This can still be overridden by setting the CMake variable
LLDB_TEST_EXECUTABLE_ARCH=(x64|x86)

This was causing core dumps on MacOSX and was not properly
cleaning up the state of the inferior before exiting.
The test was overriding def tearDown(), but failed to
call the base class after doing its own cleanup. This
essentially eliminated normal clean-up activity.

Currently, the test runner makes the assumption that it will run
commands through /bin/sh. This is obviously not true on Windows,
so this patch abstracts this logic out somewhat. Instead of
having the caller build the command string himself, the caller
will now pass in argument list of the form [[a, b], [c, d], ...]
which will get converted into a string of the form a b; c d or
a b && c d, depending on the platform.

lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module. This
Host functionality was unimplemented on Windows, so this patch
implements it. Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

99% of this CL is simply moving calls to "import pexpect" to a more
narrow scope - i.e. the function that actually runs a particular
test. This way the test suite can run on Windows, which doesn't have
pexpect, and the individual tests that use pexpect can be disabled on
a platform-specific basis.
Additionally, this CL fixes a few other cases of non-portability.
Notably, using "ps" to get the command line, and os.uname() to
determine the architecture don't work on Windows. Finally, this
also adds a stubbed out builder_win32 module.
The full test suite runs correctly on Windows after this CL, although
there is still some work remaining on the C++ side to fix one-shot
script commands from LLDB (e.g. script print "foo"), which currently
deadlock.

This fixes all of the hidden ivar test cases and any case where we try to find the full definition of an objective C class.
This also means hidden ivars show up again.

This change adds a member to the base test case for gdb-remote that
indicates whether a stub makes two X stop notification reports on kill
commands. This is set to true for debugserver tests.
The test for killing an attached process after it's first stop notification
has been modified to look at that flag and add an extra X packet matcher
so the "unmatched packet warning" doesn't get emitted for the second X on
MacOSX with debugserver.
I also broke those tests out of the monolithic TestLldbGdbServer mega test
case and put it in its own, new TestGdbRemoteKill.py file and test case.
Tested:
Ubuntu 14.04 x86_64, clang-3.5 built lldb, no test failures.
MacOSX 10.9.4, Xcode 6.0 Beta 3 built lldb, no test failures.

Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.

Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism. This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

still, which should be addressed in later commits.

The --setsid (-S) option changes the session id for the lldb-gdbserver process.
This is used by tools such as lldb-platform and allows the user to prevent
llgs from being in the same session as a calling terminal session.
This will prevents terminal group control signals from affecting
lldb-gdbserver.

The following intermittently-failing tests have been flipped from
skip to XFAIL on some combo of Linux and MacOSX:
TestCallStopAndContinue.py (Linux, MacOSX)
TestCallWithTimeout.py (Linux)
TestConvenienceVariables.py (Linux)
TestStopHookMultipleThreads.py (Linux)
The following new tests have been marked XFAIL but are just
intermittently failing:
TestMultipleDebug.py (definitely intermittent on MacOSX, not sure I've seen
it pass yet on Linux)

debug sessions simultaneously to expose race conditoin/locking
issues.
This directory has an inferior program, testprog.cpp that has a
couple of functions we can put breakpoints on.
It has a driver program, multi-process-driver.cpp, which links
against the LLDB solib and uses the SB APIs. It creates 50 pthreads,
creates a debugger on all of them, launches a debug session of the
inferior testprog, hits a couple breakpoints, walks the stack,
continues, etc., and then kills the inferior and ends the debug
session.
A pass is if all fifty debug sessions complete successfully
in the alloted time (~60 seconds).
We may need to tweak this one to work correctly on different
platforms/targets but I wanted to get it checked in to start.

and to allow that to fail more gracefully. This appears to have solved some
