Right now we just prevent such types from being on the heap. This CL makes it so they cannot appear on the stack either. The distinction between heap and stack is pretty vague at the language level (e.g. it is affected by -N), and we don't need the flexibility anyway. Once go:notinheap types cannot be in either place, we don't need to consider pointers to such types to be pointers, at least according to the garbage collector and stack copying. (This is the big win of this CL, in my opinion.) The distinction between HasPointers and HasHeapPointer no longer exists. There is only HasPointers. This CL is cleanup before possible use of go:notinheap to fix #40954.
