[dev.regabi] cmd/compile: remove Name.Class_ accessors

These aren't part of the Node interface anymore, so no need to keep
them around.

Passes toolstash -cmp.

[git-generate]
cd src/cmd/compile/internal/ir

: Fix one off case that causes trouble for rf.
sed -i -e 's/n.SetClass(ir.PAUTO)/n.Class_ = ir.PAUTO/' ../ssa/export_test.go

pkgs=$(go list . ../...)
rf '
	ex '"$(echo $pkgs)"' {
		var n *Name
		var c Class
		n.Class() -> n.Class_
		n.SetClass(c) -> n.Class_ = c
	}

	rm Name.Class
	rm Name.SetClass
	mv Name.Class_ Name.Class
'
