Summary:
This allows to run dexter tests with separately compiled
binaries that are specified via --binary if the source file
location changed between compilation and dexter test run.

Having the input dumped on failure seems like a better
default: I debugged FileCheck tests for a while without knowing
about this option, which really helps to understand failures.
Remove `-dump-input-on-failure` and the environment variable
FILECHECK_DUMP_INPUT_ON_FAILURE which are now obsolete.

When passing a test path, if the path points directly at a file, then
normcase would not be called on path.
This would change the expected lower case drive path, on windows, to be
uppercase. This patch simply calls normcase on the test path at the earliest
point possible to avoid this issue.

Summary:
It is possible that CMake tries to process debuginfo-tests before any
attempt to find Python3. Ensure that CMake attempts to find it before
complaining that it doesn't exist.

The documentation says we need python >= 3.6. Running it with an older
version, we get verbose output from python interpreter.
This patch fixes that as:
$ python2 dexter.py list-debuggers
You need python 3.6 or later to run DExTer

Add DebuggerControllerBase and DefaultController to Dexter
implements a new architecture that supports new and novel ways of running
a debugger under dexter.
Current implementation adds the original default behaviour via the new
architecture via the DefaultController, this should have NFC.

This patch addresses the issue of the regression suite not running on windows
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.

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.

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).

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.

There was CMake code that would attempt to detect Python 3 even if
LLVM was configured with Python 2, but it messed with the environment
for the other LLVM projects. This commit removes this functionality
and just lkeaves a hard error if Python < 3 is detected and
debuginfo-tests are required.
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.

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.

LLDB already requires Python 3 on Windows, so I already configure it
that way. For some reason CMake fails to find the one that Visual Studio
automatically installs at this standard location:
C:/Program Files (x86)/Microsoft Visual Studio/Shared/Python37_64/python.exe
CMake prefers the python on path, which happens to be python 2.7.
