Fixes scala#22970 Simple example showing how awkward this is compared to a traversal, where there is more control when descending. Previously, it "ignored" the LHS of Assign to avoid taking `x = y` as ref to `x` instead of assignment to. Now, "mark" the LHS as assignment, so `transformIdent` and `Select` set a "mode" flag, such that `x` is correctly taken as either a ref or assign to `x`. Probably there is more complex syntax to handle as LHS, but I haven't had coffee yet. [Cherry-picked 9bee756]
