Roger Ferrer Ibanez 6f56d3eee8 [libcxx] Define istream_iterator equality comparison operators out-of-line 
Currently libc++ defines operator== and operator!= as friend functions in the
definition of the istream_iterator class template. Such definition has a subtle
difference from an out-of-line definition required by the C++ Standard: these
functions can only be found by argument-dependent lookup, but not by qualified
lookup.

This patch changes the definition, so that it conforms to the C++ Standard and
adds a check involving qualified lookup to the test suite.

Patch contributed by Mikhail Maltsev.

Eric Fiselier 515e9dbfef Change test suite to support c++17 dialect flag instead of c++1z. 
This patch changes the test suite to attempt and prefer -std=c++17 over
-std=c++1z. It also fixes the REQUIRES and UNSUPPORTED lit markers
to refer to c++17 over c++1z.

Stephan T. Lavavej 40608ce4c9 [libcxx] [test] Be compatible with LWG 2438 "std::iterator inheritance shouldn't be mandated". 
In C++17, these iterators are allowed but not required
to inherit from the deprecated std::iterator base class.

Fixes D32727.

Mehdi Amini 2f75ad4e51 Recommit r296712: "Fix Apple-specific XFAIL directive in libc++ test" 
The test is passing with c++11 and c++14 but not c++1z on this
particular version of the compiler. Try to use lit boolean condition
to satisfy this constaint.

Mehdi Amini cd0b56c5cf Revert "Fix Apple-specific XFAIL directive in libc++ test" 
This reverts commit r296712. It broke our bot.

It turns out that the test is passing with c++11 and c++14 but
not c++1z on this particular version of the compiler. Since one
job is defaulting to c++1z and the other is testing all config I'm
not sure how to fix this...

Mehdi Amini 48c4a82105 Fix Apple-specific XFAIL directive in libc++ test 
This tests is failing in XCode 7.0. But Xcode 7.3 that shipped
an updated clang has this test passing. This is fixing green dragon
which runs this configuration.

Eric Fiselier fec6be9c81 Recommit r286884: P0503R0, adopted in Issaquah, rewords some requirements on nullptr_t and istream_iterator. 
No code changes were needed, but I updated a few tests.
Also resolved P0509 and P0521, which required no changes to the library or tests.

This patch was reverted due to llvm.org/PR31016. There is a bug in Clang 3.7
which causes default.pass.cpp to fails. That test is now marked as XFAIL for that
clang version.

This patch was originally authored by Marshall Clow.

This reverts commit r286884, because it breaks the Xcode 7 builders:

Eric Fiselier f2f2a6395f Replace __cplusplus comparisons and dialect __has_feature checks with TEST_STD_VER. 
This is a huge cleanup that helps make the libc++ test suite more portable.
