Max Kazantsev 773d488805 [IndVars][NFC] Refactor to make modifications of Changed transparent ... IndVarSimplify's design is somewhat odd in the way how it reports that some transform has made a change. It has a `Changed` field which can be set from within any function, which makes it hard to track whether or not it was set properly after a transform was made. It leads to oversights in setting this flag where needed, see example in PR38855. This patch removes the `Changed` field, turns it into a local and unifies the signatures of all relevant transform functions to return boolean value which designates whether or not this transform has made a change.
