target_family="wasm" and target feature atomics and WebAssembly only.Expand description
Corresponding intrinsic to wasm’s memory.atomic.notify instruction

indicated by ptr. Threads previously blocked with the i32_atomic_wait
and i64_atomic_wait functions above will be woken up.
The waiters argument indicates how many waiters should be woken up (a
