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.

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).

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.

[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.

a file descriptor.

Do not derive __gnu_cxx::hash<T> from std::hash<T>.

Instead, define explicit specializations for the basic types listed in
the SGI documentation. This solves two problems:
1) Helps avoid silent ODR violations caused by the absence of a
user-supplied __gnu_cxx::hash specialization in cases where a std::hash
specialization exists (e.g. for std::string).
2) __gnu_cxx::hash semantics are slightly different to those of
std::hash (for example, the former may dereference a pointer argument)
so it is inappropriate for __gnu_cxx::hash to receive std::hash
specializations by default.

Implement LWG Issue #2285 - make_reverse_iterator. Also mark issues #1450 and #2205 as complete; they are just wording changes in the standard. Mark issues #2359 , #2320 and #2322 as complete - libc++ implements them already.

More LWG issues. Mark #2182 , #2323 and #2213 as complete. Add a test for #2339 , and mark that as complete. No actual changes to the libc++ code; all of these were already in place.

Implement LWG issue 2306: match_results::reference should be value_type&, not const value_type&. This is a general move by the LWG to have the reference type of read-only containers be a non-const reference; however, there are no methods that return a non-const reference to a match_result entry, so there's no worries about getting a non-const reference to a constant object.
