[dev.regabi] cmd/compile: replace CTNIL with ONIL
Properly speaking, "nil" is a zero value, not a constant. So
go/constant does not have a representation for it. To allow replacing
Val with constant.Value, we split out ONIL separately from OLITERAL so
we can get rid of CTNIL.
Passes toolstash-check.
