The equality operators for std::allocator were throw() in C++03 and
are noexcept in C++11, but we were missing those specs (and the
problem wasn't caught by the testsuite because of PR50871).

Tested x86_64-linux, committed to trunk.

    	* include/bits/allocator.h (operator==, operator!=): Add exception
    	specifications.
