Fix atomic operations argument types

In preparation of the rework of atomic operations, all atomic function
calls are fixed to use fully supported, compatible types. This means
that atomic operations ar erestricted to 32-bit and 64-bit, and that
value types must be strictly compatible with pointer types.
