functions to protect against duration and time_point overflow. Since
we're about to wait anyway, we can afford to spend a few more cycles on
this checking. I purposefully did not treat the timed try_locks with
overflow checking. This fixes
http://llvm.org/bugs/show_bug.cgi?id=13721 . I'm unsure if the standard
needs clarification in this area, or if this is simply QOI. The
<chrono> facilities were never intended to overflow check, but just to
not overflow if durations stayed within +/- 292 years.

Solaris not providing some of the locales that the test suite uses.
Note: This depends on an xlocale (partial) implementation for Solaris and a
couple of fixed standard headers. These will be committed to a branch later
today.
