Hi All,
The following testcase:
int zoo1 (int a, int b, int c, int d)

return (a > b ? c : d) & 1;

gets de-optimized by the front-end since somewhere around GCC 4.x due to a fix
that was added to fold_binary_op_with_conditional_arg.

Add a simpler definition of std::__detected_or using concepts. This
also replaces the __detector::value_t member which should have been using
a reserved name.
Use __detected_or in pointer_traits.

I made a mistake defining fmin/fmax RTL patterns in r13-2085: I used
smin and smax in the definition mistakenly. This causes the optimizer
to perform constant folding as if fmin/fmax was "really" smin/smax
operations even with -fsignaling-nans. Then pr105414.c fails.
We don't have fmin/fmax RTL
