c++: Implement __remove_all_extents built-in trait
This patch implements built-in trait for std::remove_all_extents.
gcc/cp/ChangeLog:
* cp-trait.def: Define __remove_all_extents.
* semantics.cc (finish_trait_type): Handle
CPTK_REMOVE_ALL_EXTENTS.
gcc/testsuite/ChangeLog:
* g++.dg/ext/has-builtin-1.C: Test existence of
__remove_all_extents.
* g++.dg/ext/remove_all_extents.C: New test.
