PiperOrigin-RevId: 398257218 -- f1f9792000355eb1d0c11b17800048491662a218 by Abseil Team <absl-team@google.com>: Fix documentation for btree_multi{map,set}::merge to match behavior for elements with equivalent keys. PiperOrigin-RevId: 398071060 -- 8a9a302aebf2419e83f0c7dc5a63c33d26b807a3 by James Y Knight <jyknight@google.com>: Silence -Wunused-value warning newly emitted by ToT Clang. The value is being intentionally ignored, as the purpose of the call is only to eliminate this overload via SFINAE when `GenT{}` is not constant evaluable.
