Kyle Miller 409cbe1da9 fix: make rw collect only new goals, occurs check (#10306) ... This PR fixes a few bugs in the `rw` tactic: it could "steal" goals because they appear in the type of the rewrite, it did not do an occurs check, and new proof goals would not be synthetic opaque. This PR also lets the `rfl` tactic assign synthetic opaque metavariables so that it is equivalent to `exact rfl`. Implementation note: filtering old vs new is not sufficient. This PR partially addresses the bug where the rw tactic creates natural metavariables for each of the goals; now new proof goals are synthetic opaque. Metaprogramming API: Instead of `Lean.MVarId.rewrite` prefer `Lean.Elab.Tactic.elabRewrite` for elaborating rewrite theorems and applying rewrites to expressions.
