This patch implements built-in trait for std::is_member_object_pointer.
gcc/cp/ChangeLog:
* cp-trait.def: Define __is_member_object_pointer.
* cp-trait.gperf: Reflect cp-trait.def change.
* cp-trait.h: Likewise.
* constraint.cc (diagnose_trait_expr): Handle
CPTK_IS_MEMBER_OBJECT_POINTER.
* semantics.cc (trait_expr_value): Likewise.
(finish_trait_expr): Likewise.
gcc/testsuite/ChangeLog:
* g++.dg/ext/has-builtin-1.C: Test existence of
__is_member_object_pointer.
* g++.dg/ext/is_member_object_pointer.C: New test.
