allp now has length gomaxprocs, which means none of allp[i] are nil or
in state _Pdead. This lets replace several different styles of loops
over allp with normal range loops.
for i := 0; i < gomaxprocs; i++ { ... } loops can simply range over
allp. Likewise, range loops over allp[:gomaxprocs] can just range over
allp.
Loops that check for p == nil || p.state == _Pdead don't need to check
this any more.
Loops that check for p == nil don't have to check this *if* dead Ps
don't affect them. I checked that all such loops are, in fact,
unaffected by dead Ps. One loop was potentially affected, which this
fixes by zeroing p.gcAssistTime in procresize.
Updates #15131.
