// stack (to set up the inputs), runs the call, and the memmoves the stack back to
// the frame structure (to preserve the outputs).

// Originally reflect.call did not distinguish inputs from outputs: both memmoves
// were for the full stack frame. However, in the case where the called function was
// one of these wrappers, the rewritten receiver is almost certainly a different type

// function oclass computes the specific Ytype of an operand and then the set
// of more general Ytypes that it satisfies is implied by the ycover table, set
// up in instinit.  For example, oclass distinguishes the constants 0 and 1
// from the more general 8-bit constants, but instinit says
//
//	ycover[Yi0*Ymax+Ys32] = 1
//	ycover[Yi1*Ymax+Ys32] = 1
//	ycover[Yi8*Ymax+Ys32] = 1
