hardware. It changes the following things:

* add new dexter regression suite command to lit.cfg.py that makes use of the
  clang-cl_vs2015 and dbgend builder and debuggers.

* sprinkle the new regressionsuite command through the feature and tool tests
  that require them.

* mark certain problem tests on windows

* [revert fix] fixed darwin regression test failures by adding unsupported line
  for system-darwin to command tests.

There's a couple of tests that fail (or pass) in unexpected ways on Windows.

Problem tests are both the penalty and perfect expect_watch_type.cpp tests.
Type information reporting parity is not possible a this time in dexter due to
the nature of how different debuggers report type information back to their users.

Jeremy Morse 0a3b083791 [debuginfo-tests] Warn, not error, if we can't delete working directory
On Windows, an error running the debugger typically leaves a process
hanging around in the working directory. When Dexter exits, it can't then
delete the working directory and produces an exception, masking the problem
in the debugger. (This can be worked around by specifying --save-temps).
Rather than hard-erroring, print a warning when we can't delete the working
directory instead.

It'd be much better to improve our error handling, and make the
WorkingDirectory class aware that something's wrong when it enters exit.
However, this is something that's going to mask genuine errors and make
everyones lives harder right now, so I think this non-ideal fix is
important to get in first.

Jeremy Morse 5ee4a03bc9 [debuginfo-tests][Dexter] Fix some Windows-unfriendly Dexter behaviours
These are some minor things that I've run into on Windows, largely in
error handling paths:

 * Giving --lldb-executable on Windows triggers a "useless option" code
   path, which touches an attribute that only exists in the
   list_debuggers tool. Switch this to use hasattr, which will work in
   all subtools.
 * We were over-decoding some text reporting errors, but only in an
   exception path
 * The path to lldb on Windows needs to be quoted (even though dexter
   isn't making use of it).

Jeremy Morse 26f6aa9e3b [debuginfo-tests] Fix Dexter process creation failure on Windows
When writing the Windows dbgeng driver for Dexter, I couldn't work out why it
would either launch a process and leave it free running, or if I started the
process suspended, never do anything with it. The result was a hack to create
and attach processes manually. This has been flaking out on Reids Windows
buildbot, and clearly wasn't a good solution.

Digging into this, it turns out that the "normal" cdb / windbg behaviour of
breaking whenever we attach to a process is not the default: it has to be
explicitly requested from the debug engine. This patch does so (by setting
DEBUG_ENGOPT_INITIAL_BREAK in the engine options), after which we can simply
call "CreateProcessAndAttach2" and everything automagically works.

No test for this behaviour: everything was just broken before.

Reid Kleckner 63f49465c3 [dexter] Fix feature tests on Windows
First, add LLD as a dependency on Windows. The windows batch scripts
pass -fuse-ld=lld, so they need it.

Second, decode builder stdout/stderr even if the command fails.
Otherwise it gets printed as b'line 1\n\rline 2\n\r'.

Last, make the batch script one line less noisy. We might want to try to
do more here, though. It would be nice if we could get as close to
possible as lit, where you can literally copy & paste the failing
command to re-run it.

With the two changes above, now the feature tests that use clang++.bat
pass for me. The clang-cl_vs2015 ones still fail, and I'll fix them
separately.

Reid Kleckner 7035ea6e3e [dexter] Remove lit check for python 3
This is checking the version of Python used to run lit, which is not
necessarily the same as the version used to run the dexter tests.  If
the tests are run via the build/bin/llvm-lit[.py] helper script, then
that is likely to pick up whatever version of Python is on PATH.
Conventionally, this will find Python 2. CMake already checks that
Python 3 is in use and puts the path to it in the lit site config, so
this check is redundant, and Python 3 will ultimately be used to run
dexter.
