[PATCH 03/14] c++: Implement __is_floating_point built-in trait

This patch implements built-in trait for std::is_floating_point. gcc/cp/ChangeLog: * cp-trait.def: Define __is_floating_point. * constraint.cc (diagnose_trait_expr): Handle CPTK_IS_FLOATING_POINT. * semantics.cc (trait_expr_value): Likewise.
