As part of the call sequence, IPInt computes the address of the first non-argument Wasm stack slot and stores it on the stack to use after the call while pushing the call return values. To simplify JSPI implementation, we should store the address as a value relative to the frame pointer, so stack data can be easily moved to a different address.
