Now the registration phase looks like:
var cases [4]runtime.scases
var order [8]uint16
selectsend(&cases[0], c1, &v1)
selectrecv(&cases[1], c2, &v2, nil)
selectrecv(&cases[2], c3, &v3, &ok)
selectdefault(&cases[3])
chosen := selectgo(&cases[0], &order[0], 4)
Primarily, this is just preparation for having the compiler open-code
selectsend, selectrecv, and selectdefault.
As a minor benefit, order can now be layed out separately on the stack
in the pointer-free segment, so it won't take up space in the
function's stack pointer maps.
