Clemens Backes 729235c21a [wasm][memory64] Prepare atomic builtins for i64 indexes 
The offset (also called "address") passed to the atomic builtins was
32-bit until now. With memory64, we will have to also accept 64-bit
values there, or at least values within the allocatable memory range.
This CL thus changes the builtins to receive uintptr values instead of
uint32, and pass them on to the runtime functions as double (as before).
The runtime then casts them back to uintptr_t instead of uint32_t.

Liftoff is extended to zero-extend the uint32 value if needed. TurboFan
already passed a machine-word sized integer before.

Drive-by: Rename some "address" to "offset" to make the semantics more
clear.
