History
Yuao Ma 0772974fec libstdc++: complete P0493R5 with pointer support 
Previous implementations of fetch_min/max only supported integers, not
handling pointers. To complete the paper, we need to implement support
for pointers as well. This patch adds the missing functionality and
test cases.

libstdc++-v3/ChangeLog:

	* include/bits/atomic_base.h (__atomic_base<_PTp*>::fetch_min,
	__atomic_base<_PTp*>::fetch_max,
	__atomic_ref<_Pt, false, false, true>::fetch_min,
	__atomic_ref<_Pt, false, false, true>::fetch_max): Define new
	functions.
	* include/std/atomic (atomic<_Tp*>::fetch_min,
	atomic<_Tp*>::fetch_max): Likewise.
	(atomic_fetch_min_explicit, atomic_fetch_max_explicit,
	atomic_fetch_min, atomic_fetch_max): Change parameter from
	__atomic_base<_ITp>* to atomic<_Tp>*.
	* testsuite/29_atomics/atomic/pointer_fetch_minmax.cc: New test.
	* testsuite/29_atomics/atomic_ref/pointer_fetch_minmax.cc: New
	test.
