The loop searching for use_lldb_suite_root had a bug where if the marker
file happened to be missing, it would enter an infinite loop. While this
shouldn't happen in normal circumstances, it can happen accidentally,
and debugging it is not very pleasant.
The loop had an exit condition, but it was incorrent (os.path.dirname
returning None). This will never happen as dirname will just return the
same folder over and over again once it reaches the root folder. This
fixes the exit condition to account for that.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Python has a complicated mechanism of checking an objects truthity.
This involves a number of steps, which end with calling two private
methods on an object (if they are implemented). In Python 2 these
two methods are `__nonzero__` and `__len__`, and in Python 3 they
are `__bool__` and `__len__`. Because we *also* define a __len__
method for certain iterable types, this was triggering a situation
in Python 3 where `__nonzero__` wasn't defined, so it was calling
`__len__`, which was returning 0 (for example an SBDebugger with
no targets), and as a result the truthosity was determined to be
False.
We fix this by correctly using ` __bool__` for Python 3, and leave
the behavior under Python 2 unchanged.
Note that this fix is only implemented in the SWIG generation
python script, and not the SWIG generation shell script. Someone
more familiar than me with shell scripts will need to fix them
to support this for Python 3 if desired.

This reverts commit e59c95ca936f5a0a8abb987b8605fd8bf82b03b6.
This was a mistake on my part. The real problem was with my
environment. I was using a release interpreter to try to load
my debug extension module. I noticed this after I finally managed
to get into my extension module's init method, and then it segfaulted
with heap errors due to mismatched CRT (debug vs. release)

In Python 2, a debug extension module required an _d suffix, so
for example the extension module `_lldb` would be backed by the file
`_lldb_d.pyd` if built in debug mode, and `_lldb.pyd` if built in
release mode. In Python 2, although undocumented, this seems to
no longer be the case, and even for a debug extension module, the
interpreter will only look for the `_lldb.pyd` name.
