Optimize rules in group that only differ in filters

[quasilyte]

func strconv(m dsl.Matcher) {
	m.Match(`fmt.Sprintf("%d", $x)`).Where(m["x"].Type.Is(`int`)).Suggest(`strconv.Atoi($x)`)

	m.Match(`fmt.Sprintf("%d", $x)`).
		Where(m["x"].Type.Is(`int64`)).
		Suggest(`strconv.FormatInt($x, 10)`)

	m.Match(`fmt.Sprintf("%d", $x)`).
		Where(m["x"].Type.OfKind(`int`)).
		Suggest(`strconv.FormatInt(int64($x), 10)`)

	m.Match(`fmt.Sprintf("%d", $x)`).
		Where(m["x"].Type.OfKind(`uint`)).
		Suggest(`strconv.FormatUint(uint64($x), 10)`)
}

In the example above, we have 4 rules that have identical syntax patterns.
We should be able to merge them and branch by their filter conditions.

syntax pattern 1
  -- filter 1 -- action 1
  -- filter 2 -- action 2
  -- filter 3 -- action 3
  -- filter 4 -- action 4
