A bunch more simplification and refactoring to the constraint solver * Instead of Untouchables being a [Unique], it is simply an Int indicating the depth of nesting. This works fine now that floatEqualities is promoting the floated unification variables to the outer level * Remove the inert_tv_eqs (InScopeSet) from InertCans. It wasn't being used. See Note [Shadowing in a constraint] in TcRnTypes * Rename inert_frozen to inert_insols * Some simple refactoring in TcErrors.reportFlatsAndInsols TcInteract.kickOutRewritable TsSimplify.floatEqualities

Fail earlier if there's an error in a type declaration This change means that we don't recover from erroneous type declarations, thereby reporting fewer errors. But trying to recover confused GHC (leading to a pattern match failure in the compiler Trac #7175), and it turned out to be tricky to fix that. So this patch takes the more conservative path of failing earlier, perhaps reporting fewer real errors. MERGED from commit d0ddde58f928a6b156d8061c406226c4fbb7cd22

Retain ordering of finalizers during GC (#7160) This came up since the addition of C finalizers, since Haskell finalizers are already stored in an explicit list. C finalizers on the other hand get a WEAK object each, so in order to run them in the right order we have to make sure that list stays in the correct order. I hate adding new invariants, but this is the quickest way to fix the bug for now. A better way to fix it would be to have a single WEAK object with a list of finaliers attached to it, and a primop for adding finalizers to the list.

More simplifications to the constraint solver * inert_solved becomes dictionaries-only, inert_solved_dicts * inert_solved_dicts is used only to cache the result of uses of a top level instance declaration, just like inert_solved_funeqs * That in turn simplifies xCtFlavor and rewriteCtFlavor, because they no longer need a "should I cache" parameter. (Moreover the settings for this parameter were very subtle; it's easy to get loops if you cache too much. Caching only top-level instance uses is much safer, and eliminates all these subtle cases.)
