Marshall Clow 89872e99a5 Fix a problem with reference_wrapper in C++03 that was causing counting predicates to fail. Add a test to make sure it works. However, most of the reference_wrapper tests still fail in C++03 mode, due to a lack of decltype. No change there.

Dan Albert a85b27f6f7 Add locales to available_features for tests.
Linux has a lot of failures caused by not having support for certain
locales. Since these come out as a lot of noise in the test results,
have lit.cfg detect the presence of the various locales used in the
tests and add them to config.available_features as locale.LOCALE_NAME.

This patch also adds REQUIRES: locale.REQUIRED_LOCALE to every test that
I saw failing in this manner. We probably need to add more for all the
tests requiring en_US.UTF-8, but we can do that on an as-needed basis.

One thing that concerns me is how many tests get skipped because of
missing locales (especially in regex/). We should make a point of
splitting up any tests that test default behavior _and_ behavior under a
given locale so that we aren't losing coverage for default behavior.

Dan Albert 15c010a37e Base regex code on char_class_type.
__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.

This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Eric Fiselier aa873af53d [libcxx] expose experimental::erased_type for all standard versions.
Summary: The polymorphic allocator implementation would greatly benefit by defining virtual functions in the dynlib instead of inline. In order to do that some types are going to have to be available outside of c++1y. This is the first step.

David Majnemer 8b51260274 Fix std::make_heap's worst case time complexity
std::make_heap is currently implemented by iteratively applying a
siftup-type algorithm.  Since sift-up is O(ln n), this gives
std::make_heap a worst case time complexity of O(n ln n).

The C++ standard mandates that std::make_heap make no more than O(3n)
comparisons, this makes our std::make_heap out of spec.

Fix this by introducing an implementation of __sift_down and switch
std::make_heap to create the heap using it.
This gives std::make_heap linear time complexity in the worst case.

This fixes PR20161.

Eric Fiselier 531d8b2bc4 [libcxx] Add <experimental/utility> header for LFTS.
Summary:
This patch adds the `<experimental/utility>` header as specified in the latest draft of the library fundamentals TS.

`<experimental/utility>` only contains `class erased_type`. 

This patch also updates the documentation to list the `erased_type` class as "initial implementation complete".

Test Plan:
Three test cases where added:

1. Test that `_LIBCPP_VERSION` is defined.
2. Test that `<utility>` has been included.
3. Test that `erased_type` is in the correct namespace and is constexpr default constructible.

David Majnemer 1e9592a9c7 [libc++] random_device fails if open returns zero
random_device::random_device(const string&) wrongly assumes that open
can only validly return a file descriptor greater than zero.

This results in random_device believing that it didn't successfully open
the device causing it to throw in it's constructor, this ends up leaking
a file descriptor.

The fix is simple, don't error on file descriptors which are zero.

Other tests in this directory use this type, so it's probably copypasta from

(test_buf only forwards to the superclass in all tests where it's used though,
so I wonder if it can be replaced with just using filebuf / wfilebuf
everywhere?)

error_condition(posv, generic_category()) if ev could map to a POSIX
errno.

Linux reserves up to and including 4095 for errno values, use this as a
bound.
