Robert Griesemer 589e32dbdf [dev.typeparams] cmd/compile/internal/types2: replace Sum type with Union type
- We still mostly ignore the tilde information.

- More consistent naming: A Union term is the pair (type, tilde).
  Rename Union.terms to Union.types; the Union.types and Union.tilde
  slices make up the Union terms.

- Replace Sum.is with Union.underIs: underIs iterates through all
  union terms and calls its argument function with the underlying
  type of the term (and thus can ignore the tilde information).
  This also eliminates the need to call under in the argument
  function.

- Added Union.is for situations where we need to consider the tilde
  information for each Union term.
