Joseph Myers e400a64936 c: C2x binary constants ...

C2x adds binary integer constants (approved at the last WG14 meeting,
though not yet added to the working draft in git).  Configure libcpp
to consider these a standard feature in C2x mode, with appropriate
updates to diagnostics including support for diagnosing them with
-std=c2x -Wc11-c2x-compat.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.
