Summary:
Update makefiles to specify -fPIC in Makefile.rules and only throw -fPIC when building a shared library. This change is necessary to allow building the lldb tests on Windows where -fPIC is not a valid option.
Update a few places to Python 3.x syntax

This patch creates a <test>.dwarf, <test>.dwo, etc., build directory for each testcase variant.
Most importantly, this eliminates the need for the per-test lock file in the source directory.
Tests that are marked as NO_DEBUG_INFO_TESTCASE and build with
buildDefault() are built in a <test>.default build directory.

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

The test works fine on linux, and I believe other targets should not
have an issue with as well. If they do, we can start blacklisting
instead of whitelisting.
The idea of using "-1" as the value of the pointer on non-apple targets
backfired, as it fails the "address != LLDB_INVALID_ADDRESS" test (-1 is
the value of LLDB_INVALID_ADDRESS). However, it should be safe to use
0x100 for other targets as well. The first page of memory is generally
kept unreadable to catch null pointer dereferences.

Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point. Both devices pass the testsuite without
any errors or failures.
I have seen some instability with the armv7 test runs, I may submit additional patches
to address this. arm64 looks good.
I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same. I know it's a rather large patch.
One change I had to make specifically for iOS devices was that debugserver can't
create files. There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file. They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.

There will be some smaller follow-on patches. The changes to tools/lldb-server are
verbose and I'm not thrilled with having to skip all of these tests manually.
There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64"
means it's an ios device, and I need to review & clean these up with an OS check
as well. (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't
cause problems, but it's not an assumption I want to rely on).

*** 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.

A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.
These two test cases:
tools/lldb-server/lldbgdbserverutils.py
python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.
These test cases:
functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
python_api/sbdata/TestSBData.py (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly. For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.
These test case:
python_api/sbdata/TestSBData.py (second change)
functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.

previously, I have marked only one test as flaky, but now I noticed another test failing with the

SBProcess::ReadMemory and other related functions such as
WriteMemory are returning Python string() objects. This means
that in Python 3 that are returning Unicode objects. In reality
they should be returning bytes objects which is the same as a string
in Python 2, but different in Python 3. This patch updates the
generated SWIG code to return Python bytes objects for all
memory related functions.
One quirk of this patch is that the C++ signature of ReadCStringFromMemory
has it writing c-string data into a void*. This confuses our swig
typemaps which expect that a void* means byte data. So I hacked up
a custom typemap which maps this specific function to treat the
void* as string data instead of byte data.

This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party
libraries. Packages themselves shouldn't need to import it,
because by the time it gets into the package, the top-level
script should have already done this. Indeed, it was just
adding the same values to sys.path multiple times, so this
patch is essentially no functional change.
To make sure it doesn't get re-introduced, we also delete the
`use_lldb_suite` module from `lldbsuite/test`, although the
original copy still remains in `lldb/test`

For convenience, we had added the folder that dotest.py was in
to sys.path, so that we could easily write things like
`import lldbutil` from anywhere and any test. This introduces
a subtle problem when using Python's package system, because when
unittest2 imports a particular test suite, the test suite is detached
from the package. Thus, writing "import lldbutil" from dotest imports
it as part of the package, and writing the same line from a test
does a fresh import since the importing module was not part of
the same package.
The real way to fix this is to use absolute imports everywhere. Instead
of writing "import lldbutil", we need to write "import
lldbsuite.test.util". This patch fixes up that and all other similar
cases, and additionally removes the script directory from sys.path
to ensure that this can't happen again.

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package. This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
