SI-9630 Fix spurious warning related to same-named case accessors
Hash consing of trees within pattern match analysis was broken, and
considered `x1.foo#1` to be the same tree as `x1.foo#2`, even though
the two `foo`-s referred to different symbols.
The hash consing was based on `Tree#correspondsStructure`, but the
predicate in that function cannot veto correspondance, it can only
supplement the default structural comparison.
I've instead created a custom tree comparison method for use in
the pattern matcher that handles the tree shapes that we use.
