[dev.regabi] cmd/compile: delete n.List after collapsing OADDSTR to OLITERAL
The leftover n.List is clearly unnecessary, but it makes the
inlining cost of the expression unnecessarily high.
This change breaks toolstash -cmp:
# cmd/internal/src
toolstash: compiler output differs, with optimizers disabled (-N)
inconsistent log line:
/tmp/go-build866291351/b230/_pkg_.a.log:77:
/Users/rsc/go/src/cmd/internal/src/pos.go:275:6: can inline (*PosBase).SymFilename with cost 9 as: method(*PosBase) func() string { if b != nil { return b.symFilename }; return "gofile..??" }
/tmp/go-build866291351/b230/_pkg_.a.stash.log:77:
/Users/rsc/go/src/cmd/internal/src/pos.go:275:6: can inline (*PosBase).SymFilename with cost 11 as: method(*PosBase) func() string { if b != nil { return b.symFilename }; return "gofile..??" }
Separated from other constant work so that the bigger CL can pass toolstash -cmp.
