Research direction
Read the linked LWG4291 specification issue first, then locate the libc++ implementation of map's explicit Allocator constructor and its related tests. Confirm the current constexpr support and determine the expected standard-conformance change. Done means the constructor matches LWG4291 and the relevant tests pass.
