Matthew Dempsky 6db970e20a [dev.regabi] cmd/compile: rewrite Aux uses of ir.Node to *ir.Name [generated]
Now that the only remaining ir.Node implementation that is stored
(directly) into ssa.Aux, we can rewrite all of the conversions between
ir.Node and ssa.Aux to use *ir.Name instead.

rf doesn't have a way to rewrite the type switch case clauses, so we
just use sed instead. There's only a handful, and they're the only
times that "case ir.Node" appears anyway.

The next CL will move the tag method declarations so that ir.Node no
longer implements ssa.Aux.

Passes buildall w/ toolstash -cmp.

Updates #42982.

[git-generate]
cd src/cmd/compile/internal
sed -i -e 's/case ir.Node/case *ir.Name/' gc/plive.go */ssa.go

cd ssa
rf '
ex . ../gc {
  import "cmd/compile/internal/ir"

  var v *Value
  v.Aux.(ir.Node) -> v.Aux.(*ir.Name)

  var n ir.Node
  var asAux func(Aux)
  strict n        # only match ir.Node-typed expressions; not *ir.Name
  implicit asAux  # match implicit assignments to ssa.Aux
  asAux(n)        -> n.(*ir.Name)
}
