Dimitry Andric 9729cf0934 Update libc++ to 3.8.0. Excerpted list of fixes (with upstream revision 
numbers):

r242679 Implement the plugin-based version of std::search. There are no
        searchers yet; those are coming soon.
r242682 Implement the default searcher for std::experimental::search.
r243728 Add <experimental/any> v2.
r245330 implement more of N4258 - Cleaning up noexcept in the standard
        library. Specifically add new noexcept stuff to vector and
	string's move-assignment operations
r245334 Fix PR22606 - Leak pthread_key with static storage duration to
        ensure all of thread-local destructors are called.
r245335 Fix PR23589: std::function doesn't recognize null pointer to
        varargs function.
r247036 Implementation of Boyer-Moore and Boyer-Moore-Horspool
        searchers for the LFTS.
r249325 Implement LWG#2063, and update the issues links to point to the
        github generated pages
r249738 Split <ctype.h> out of <cctype>.
r249739 Split <errno.h> out of <cerrno>.
r249740 Split <float.h> out of <cfloat>.
r249741 Split <inttypes.h> out of <cinttypes>.
r249742 Split <math.h> out of <cmath>.
r249743 Split <setjmp.h> out of <csetjmp>.
r249761 Split <stddef.h> out of <cstddef>.
r249798 Split <stdio.h> out of <cstdio>.
r249800 Split <stdlib.h> out of <cstdlib>.
r249889 Split <wchar.h> out of <cwchar>.
r249890 Split <wctype.h> out of <cwctype>.

r250254 ABI versioning macros for libc++.
r251246 Fix LWG#2244: basic_istream::seekg
r251247 Fix LWG#2127: Move-construction with raw_storage_iterator.
r251253 Fix LWG#2476: scoped_allocator_adaptor is not assignable
r251257 Fix LWG#2489: mem_fn() should be noexcept
r251618 Implement P0004R1 'Remove Deprecated iostreams aliases'
r251766 Implement the first part of P0006R0: Adopt Type Traits Variable
        Templates for C++17.
r252195 Implement P0092R1 for C++1z
r252350 Allow deque to handle incomplete types.
r252406 More of P0006R0: type traits variable aliases for C++17.
r252407 Implement LWG#2353: std::next is over-constrained
r252905 Implement P0074: Making owner_less more flexible
r253215 Implement P0013R1: Logical Operator Type Traits.
r253274 Implement P0007: Constant View: A proposal for a std::as_const
        helper function template.
r254119 Add static_assert to set/multiset/map/multimap/forward_list/deque
        that the allocator's value_type match the container's value_type.
r254283 Implement more of P0006; Type Traits Variable Templates.
r255941 LWG2485: get() should be overloaded for const tuple&&.
r256325 Fix LWG Issue #2367 - Fixing std::tuple and std::pair's default
        constructors.
r256652 Fix for ALL undefined behavior in <list>.
r256859 First half of LWG#2354: 'Unnecessary copying when inserting
        into maps with braced-init syntax'
