[committed] libstdc++: Add suggestion to std::uncaught_exception() warning

[Jonathan Wakely]

Tested powerpc64le-linux, pushed to trunk.


We should use the SUGGEST macro for std::uncaught_exception()
deprecation warnings.

libstdc++-v3/ChangeLog:

	* include/bits/allocator.h: Qualify std::allocator_traits in
	deprecated warnings.
	* libsupc++/exception (uncaught_exception): Add suggestion to
	deprecated warning.
