// pause sets SP to newsp and pauses the execution of Go's WebAssembly
// code until an event is triggered, or call back into Go.
//
// Note: the epilogue of pause pops 8 bytes from the stack, so when
// returning to the host, the SP is newsp+8.
// If we want to set the SP such that when it calls back into Go, the
// Go function appears to be called from pause's caller's caller, then
// call pause with newsp = internal/runtime/sys.GetCallerSP()-16 (another 8 is
// the return PC pushed to the stack).
