Implement LWG issue #2135 . If something goes wrong in condition_variable::wait, call terminate() rather than throwing an error. Do this indirectly, by marking the call as 'noexcept'. This is better than just calling terminate() directly, because it gives a better error message on the console.

rewrite of the requirements for forward progress, and again, requires no changes

Mark LWG Issue #2288 as complete. This was wording cleanup, no code changes required.
...
Also mark #2104 as complete. Leave the implementation in libc++ as noexcept, since
implementations are allowed to add noexcept to non-virtual calls. If we throw from
unique_lock& operator=(unique_lock&& u), then that means the preconditions were violated,
and calling terminate() (as a result of throwing from a noexcept function) is as
good example of undefined behavior as any other.

build: remove unnecessary modification of CMAKE_REQUIRED_DEFINITIONS

This is unnecessary now that the flag handling has been fixed. The flags will
be added properly in the main CMakeLists.txt after the config-ix inclusion which

build: fix erroneous overwriting of flags
...
Always use list(APPEND) as it will perform the desired action even if the list
is empty or previously unset. The first set is harmless, however, the
subsequent set was overwriting the previous flag setup resulting in an improper
compilation command being generated. This manifested as a build failure on
Linux when using cmake + ninja.

add_definitions is meant for adding C preprocessor definitions. Modern cmake

already requiring a new enough cmake.

Implement LWG 2360: 'reverse_iterator::operator*() is unimplementable'. Note that this is a (small) behavior change in the library. Reverse iterators whose base iterators' operator* return references to 'within themselves' have been sacrificed to the greater goal of avoiding data races.

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.

Two drive-by fixes as well: add a missing explicit in <deque>, and remove a tab that snuck into a container test. This issue is also LLVM bug 15724, and resolves it.
