Ensure that early-bound function lifetimes are always 'local' During borrowchecking, we treat any free (early-bound) regions on the 'defining type' as `RegionClassification::External`. According to the doc comments, we should only have 'external' regions when checking a closure/generator. However, a plain function can also have some if its regions be considered 'early bound' - this occurs when the region is constrained by an argument, appears in a `where` clause, or in an opaque type. This was causing us to incorrectly mark these regions as 'external', which caused some diagnostic code to act as if we were referring to a 'parent' region from inside a closure. This PR marks all instantiated region variables as 'local' when we're borrow-checking something other than a closure/generator/inline-const. 2021-12-31 16:55:34 -05:00			\| ^^^^^^^^^^^ associated function was supposed to return data with lifetime `'2` but it is returning data with lifetime `'1`
