re PR tree-optimization/88775 (Optimize std::string assignment)

PR tree-optimization/88775
* include/bits/stl_function.h (greater<_Tp*>::operator(),
less<_Tp*>::operator(), greater_equal<_Tp*>::operator(),
less_equal<_Tp*>::operator()): Use __builtin_is_constant_evaluated
instead of __builtin_constant_p if available.  Don't bother with
the pointer comparison in C++11 and earlier.
