Summary:
lldb-server tests are currently being skipped on the
check-lldb target. This is because we get the path of
lldb-server by modifying the path to the lldb executable.
However, by this point, we've changed directories, and a
relative path to the build/bin directory will no longer point
to the location of lldb-server.
Storing an absolute path solves this issue.

This change moves all the test event handling and its related
ResultsFormatter classes out of the packages/Python/lldbsuite/test dir
into a packages/Python/lldbsuite/test_event package. Formatters are
moved into a sub-package under that.
I am limiting the scope of this change to just the motion and a few
minor issues caught by a static Python checker (e.g. removing unused
import statements).
This is a pre-step for adding package-level tests to the test event
system. I also intend to simplify test event results formatter selection
after I make sure this doesn't break anybody.

The race boiled down to this:
If a test worker queue is able to run the test inferior and
clean up before the dosep.py listener socket is spun up, and
the worker queue is the last one (as would be the case when
there's only one test rerunning in the rerun queue), then
the test suite will exit the main loop before having a chance
to process any test events coming from the test inferior or
the worker queue job control.
I found this race to be far more likely on fast hardware.
Our Linux CI is one such example. While it will show
up primarily during meta test events generated by
a worker thread when a test inferior times out or
exits with an exceptional exit (e.g. seg fault), it only
requires that the OS takes longer to hook up the
listener socket than it takes for the final test inferior
and worker thread to shut down.

Summary:
The original breakpoint location test was failing for linux, because the compilers here tend to
merge the full-object and subobject destructors even at -O0 (as a result, we are getting only 2
breakpoint locations, and not 4 as the test expected. The fixup in r266164 substantially weakened
the test, as it now did not check whether both kinds of destructors were being found.
Because of these contraints, I have altered the logic of the test. It sets the
breakpoint by name, and then independently verifies that the breakpoint is set on the correct
demangled symbol name (which is not very meaningful since both kinds of destructors demangle to
the same name) *and* the correct symbol address (which is obtained by looking up the mangled
symbol name).

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)

This fixes several test case failure on s390x caused by the fact that
on this platform, the default "char" type is unsigned.
- In ClangASTContext::GetBuiltinTypeForEncodingAndBitSize we should return
an explicit *signed* char type for encoding eEncodingSint and bit size 8,
instead of the default platform char type (which may be unsigned).
This fix matches existing code in ClangASTContext::GetIntTypeFromBitSize,
and fixes the TestClangASTContext.TestBuiltinTypeForEncodingAndBitSize
unit test case.
- The test/expression_command/char/TestExprsChar.py test case is known to
fail on platforms defaulting to unsigned char (pr23069), and just needs
to be xfailed on s390x like on arm.
- The test/functionalities/watchpoint/watchpoint_on_vectors/main.c test
case defines a vector of "char" and implicitly assumes to be signed.
Use an explicit "signed char" instead.

This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform
This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).
There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).
The implementation follows existing platforms in a mostly straightforward
manner. A couple of things that are different:
- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
since some registers (access register) reside at offsets in the user area
that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
accessing aligned 8-byte blocks in the user area. Instead, we use a s390
specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
allows accessing a whole block of the user area in one go, so in effect
allowing to treat parts of the user area as register sets.
- SystemZ hardware does not provide any means to implement read watchpoints,
only write watchpoints. In fact, we can only support a *single* write
watchpoint (but this can span a range of arbitrary size). In LLDB this
means we support only a single watchpoint. I've set all test cases that
require read watchpoints (or multiple watchpoints) to expected failure
on the platform. [ Note that there were two test cases that install
a read/write watchpoint even though they nowhere rely on the "read"
property. I've changed those to simply use plain write watchpoints. ]

result_formatter used inspect.getfile() to get the python file name, which returned "*.pyc" if
the bytecode file was present. This resulted in files being displayed with the wrong extension,
and more critically, would confuse the rerun logic because it would try to rerun the pyc file
(which resulted in an empty rerun list as unittest refused to run those).
Fix: use inspect.getsourcefile() instead.
I am not sure why does was not an issue before. I can only assume that some system update
tricked python into producing bytecode files more aggressively.

The result variables aren't useful, and if you have a breakpoint on a
common function you can generate a lot of these. So I changed the
code that checks the condition to set ResultVariableIsInternal in the
EvaluateExpressionOptions that we pass to the execution.
Unfortunately, the check for this variable was done in the wrong place
(the static UserExpression::Evaluate) which is not how breakpoint
conditions execute expressions (UserExpression::Execute). So I moved
the check to UserExpression::Execute (which Evaluate also calls) and made the
overridden method DoExecute.

This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers). These assumptions are not always
true.
I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
every variable in a register. Sometimes the compiler
is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
to be in a register.
This test probably passes on a whole lot more systems than it
used to now. This is certainly true on OS X.

Summary:
There was a bug in linux core file handling, where if there was a running process with the same
process id as the id in the core file, the core file debugging would fail, as we would pull some
pieces of information (ProcessInfo structure) from the running process instead of the core file.
I fix this by routing the ProcessInfo requests through the Process class and overriding it in
ProcessElfCore to return correct data.
A (slightly convoluted) test is included.

Teach LLDB that different shells have different characters they are sensitive to, and use that knowledge to do shell-aware escaping
This helps solve a class of problems on OS X where LLDB would try to launch via sh, and run into problems if the command line being passed to the inferior contained such special markers (hint: the shell would error out and we'd fail to launch)
This makes those launch scenarios work transparently via shell expansion
Slightly improve the error message when this kind of failure occurs to at least suggest that the user try going through 'process launch' directly

Debug info is used only by the client and lldb-server tests do not even have the client component
running, as they communicate with the server directly. Therefore, running the tests for each
