Mark LWG issues #2075 and #2142 as complete. 2142 was a change to the standard
to remove redundant wording, which required no changes to libc++. 2075 was a 
rewrite of the requirements for forward progress, and again, requires no changes
to the library.

Add tests that should fail when lock() throws. THis is part of LWG issue #2135. No library changes here.

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.

ARM64: compare RTTI names as strings

ARM64 generates RTTI with hidden visibility, which means that typeinfo
must be compared char-by-char since it's not guaranteed to be uniqued
across the whole program.
