471932de24 Force c++14 when running tests on Windows.
VS 2015 and higher begin making use of c++14 in their standard
library headers.  As such, -std=c++11 makes it so you can't compile
trivial programs.  Bump this to -std=c++14 when this situation is
detected.

87daab322f Revert "Fix tests on Windows."
This reverts commit 9b757b6e3946311802972409f38c6cefbea917b3.

This seems to cause strange breakages about on Ubuntu.

4349e8f9b0 Fix tests on Windows.
This wasn't actually a problem with the reformat, but rather a
problem with Visual Studio 2015 Update 3, which uses some c++14
features in its standard libraries.  So we had to change -std=c++11
to -std=c++14.

f343968f5d Delete Host/windows/win32.h
It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.

This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.

There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.

This patch depends on LLVM revision r278170.

fa3d652d26 [test] [linux] define PR_SET_PTRACER constants if the system does not provide them
Android API <= 16 header do not have these symbols defined, but the kernel does support the
relevant calls. And in general, since these calls are on a best-effort basis, it won't hurt even
if we try to run in on a really ancient kernel.

ff8e6a763f Fix libstdc++ failure where <atomic> is not able to be imported on Darwin systems.
The adding of <atomic> to test_common.h broke 12 tests on Darwin. We work around this by not including <atomic> when building on darwin for libstdc++ tests.

ebc7135f8e Fix race in TestExitDuringStep and unify pseudo_barrier handling
Summary:
TestExitDuringStep was very rarely hanging on the buildbots. I can't be sure, but I believe this
was because of the fact that it declared its pseudo_barrier variable as "volatile int", which is
not sufficient to guarantee corectness (also, all other tests used atomic variables for this, and
they were passing reliably AFAIK). Besides switching to an atomic variable in this test as well,
I have also took this opportunity to unify all the copies of the pseudo_barrier code to a single
place to reduce the chance of this happening again.

bb00d0b6b2 Support Linux on SystemZ as platform
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. ]

d0f89cd721 Centralize the handling of attach permissions on linux in tests
Summary:
On linux we need the process to give us special permissions before we can attach to it.
Previously, the code for this was copied into every file that needed it. This moves the code to a
central place to reduce code duplication.

d8335e9ab4 Read macro info from .debug_macro section and use it for expression evaluation.
Summary:
DWARF 5 proposes a reinvented .debug_macro section. This change follows
that spec.

Currently, only GCC produces the .debug_macro section and hence
the added test is annottated with expectedFailureClang.

0ecdae1bdc Merge ENABLE_THREADS and ENABLE_STD_THREADS markers
Both of these markers are used in the test suit for annotating when a
test needs multi threaded support. Previously they had slightly
different meening but they converged to the point where they are used
interchangably. This CL removes the ENABLE_STD_THREADS one to simplify
the test suite and avoid some confusion.

7aac24805b Pass -fms-compatibility-version when building test inferiors.
-fms-compatibility-version defaults to VS 2013.  When using
VS 2015, this will lead to compilation failures of the test
inferiors in the C++ standard library for language conformance
reasons.

The fix here is to simply pass -fms-compatibility-version=19.0 when
we detect that a VS 2015 compiler is present.  Even though we're
actually using clang to do the compilation, clang uses this same
detection algorithm to determine the location of the standard
library.  So this check is tantanmount to saying "If clang is going
to find MSVC 2015's standard library, then pass 19.0 for
-fms-compatibility-version.

5f92a130ff Teach LLDB how to directly launch processes on the iOS simulator
This allows for command-line debugging of iOS simulator binaries (as long as UI is not required, or a full UI simulator has previously been otherwise launched), as well as execution of the LLDB test suite on the iOS simulator

This is known to compile on OSX 10.11 GM - feedback from people on other platforms and/or older versions of OSX as to the buildability of this code is greatly appreciated

c432c8f856 Move lldb/test to lldb/packages/Python/lldbsuite/test.
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`).
