Dan Albert 0bb696800f PR20546: Fix tests for compare_exchange_weak.
These calls are allowed to fail spuriously.

29.6.5.25:

    Remark: A weak compare-and-exchange operation may fail spuriously.
    That is, even when the contents of memory referred to by expected
    and object are equal, it may return false and store back to expected
    the same memory contents that were originally there. [ Note: This
    spurious failure enables implementation of compare and-exchange on a
    broader class of machines, e.g., load-locked store-conditional
    machines. A consequence of spurious failure is that nearly all uses
    of weak compare-and-exchange will be in a loop.

To fix this, we replace any assert() that expects
std::atomic::compare_exchange_weak() to return true with a loop. If the
call does not return true within N runs (with N currently equal to 10),
then the test fails.

Justin Bogner 2cfd1fed21 test: Make it possible to opt in to use_clang_verify per test
This modifies the use_clang_verify parameter I added in r217009 to
only apply to tests that specifically ask for it via // USE_VERIFY.
This allows us to incrementally convert tests, but start enjoying the
benefits right away.

Suggested by Eric Fiselier in code review.

Justin Bogner 33a2a2ed1a test: Allow using clang -verify for failures rather than exit 1
Currently, failure tests work by checking that compilation exits 1.
This can lead to tests that fail for the wrong reason, so it'd be
preferable to convert them to check for specific errors.

This adds use_clang_verify parameter that runs failure tests using
clang's -verify flag. I'll convert some tests in subsequent commits,
and once all of the tests are converted we should key this on whether
cxx_under_test is clang.

I've also converted one of the unique.ptr tests, since it's the one
that motivated the idea of using clang -verify when possible in the
review of r216317.

Eric Fiselier 7d1c2d8878 Mark test types for <atomic> nothrow default constructible. Patch from Steve MacKenzie.
The way the standard currently specifies the default constructor for atomic<T>
requires T to be nothrow default constructible. This patch makes our test types
meet this requirement.

Note: The nothrow default constructible requirment is subject to the outcome of
LWG issue 1265.

Jonathan Roelofs 16bb38907c Revert r216497: "[libcxx] Fix ctype_byname<wchar_t>::do_is() mask checking."
After discussing implementing more tests for this with @danalbert & @mclow, I
realized this change is not correct.

The C++ standard requires do_is() to behave as if it were a loop that checked
is(). Furthermore, it requires is() to check "The first form returns the result
of the expression (M & m) != 0; i.e., true if the character has the
characteristics specified"... which the reverted patch definitely does not
conform to. Even further, furthermore, this requires that ctype's mask be an
actual bitmask, unlike what android and newlib provide for _ctype_.

Fixing the original bug that instigated this patch remains TBD.

Dan Albert ae2526b4cd Refactor lit.cfg.
The purely imperative format of the configuration performed in lit.cfg
was making merge conflicts with changes I have for Android an
unbelievable pain in the ass. I've moved all of the configuration into a
Configuration class, with each piece of configuration happening in a
different method. This way I can avoid merge conflicts, and any new
features that get added (as have been done with the sanitizers, the -std
flag, etc.) can be easily applied to Android as well.

Eric Fiselier 0058c80cc7 [libcxx] Add support for LLVM_USE_SANITIZER to libcxx when being built standalone and in-tree
Summary:
This patch adds support for LLVM_USE_SANITIZER when being built in-tree and standalone. 

This patch does the following things:
1. define the LLVM_USE_SANITIZER option to "" when being built standalone. This also helps show we support it.
2. Translate LLVM_USE_SANITIZER when standalone in a very similar way done in llvm/cmake/HandleLLVMOptions.cmake.
3. Add config.llvm_use_sanitizer to lit.site.cfg.in
4. Add code to translate config.llvm_use_sanitizer's value into the needed compile flags in lit.cfg.

Currently lit.cfg assumes that that the compiler supports '-fno-omit-frame-pointer' while CMakeLists.txt actually checks to see if its supported. We could pass this information to lit but I'm not sure its needed.

Summary:
This patch does two things:
CMake Update:
  - Add compiler flag checks for -std=c++11 and -std=c++1y and remove check for -std=c++0x.
  - Add configuration option LIBCXX_ENABLE_CXX1Y to prevent/allow -std=c++1y from being chosen as the std version. LIBCXX_ENABLE_CXX1Y is set to OFF by default.
  - if LIBCXX_ENABLE_CXX1Y is enabled then set LIBCXX_STD_VERSION to c++1y and fail if the compiler does not support -std=c++1y
  - If c++1y is not enabled then use c++11 and fail if the compiler does not support c++11.

Lit Update:
  - Update lit.site.cfg.in to capture LIBCXX_STD_VERSION information as config.std.
  - Remove mentions of has_cxx0X configuration option.
  - Check for `--param std=X' passed to lit on the command line.
  - Choose the std for the tests either from command line parameter or (if it doesn't exist) the lit.site.cfg.
