runtime: clean up some silly allp loops
Back in the day, allp was just a pointer to an array. As a result, the
runtime has a few loops of the form:
for i := 0; ; i++ {
p := allp[i]
if p == nil {
break
}
...
}
This is silly now because it requires that allp be one longer than the
maximum possible number of Ps, but now that allp is in Go it has a
length.
Replace these with range loops.
