This is a fix for the -msan option when using cgo callbacks. A cgo callback works by writing out C code that puts a struct on the stack and passes the address of that struct into Go. The result parameters are fields of the struct. The Go code will write to the result parameters, but the Go code thinks it is just writing into the Go stack, and therefore won't call msanwrite. This CL adds a call to msanwrite in the cgo callback code so that the C knows that results were written.
