Matthew Dempsky 64cd6faa13 [dev.unified] cmd/compile/internal/noder: simplify mixed tag/case RTTI wiring
The previous CL largely removed the need for worrying about mixed
tag/case comparisons in switch statements by ensuring they're always
converted to a common type, except for one annoying case: switch
statements with an implicit `true` tag, and case values of interface
type (which must be empty interface, because `bool`'s method set is
empty).

It would be simpler to have writer.go desugar the implicit `true`
itself, because we already handle explicit `true` correctly. But the
existing code already works fine, and I don't want to add further
complexity to writer.go until dictionaries and stenciling is done.
