52c74e63da Auto merge of #21692 - pnkfelix:fsk-fix-coerce-match-20055, r=eddyb 
trans: When coercing to `Box<Trait>` or `Box<[T]>`, leave datum in it's original L-/R-value state.

This fixes a subtle issue where temporaries were being allocated (but not necessarily initialized) to the (parent) terminating scope of a match expression; in particular, the code to zero out the temporary emitted by `datum.store_to` is only attached to the particular match-arm for that temporary, but when going down other arms of the match expression, the temporary may falsely appear to have been initialized, depending on what the stack held at that location, and thus may have its destructor erroneously run at the end of the terminating scope.

FIx #20055.

(There may be a latent bug still remaining in `fn into_fat_ptr`, but I am so annoyed by the test/run-pass/coerce_match.rs failures that I want to land this now.)

7ea93abfb2 Auto merge of #21691 - edwardw:double-closure, r=nikomatsakis 
It was considered to be impossible but actually it can
happen for nested closures. Also, because there must
be nested closures when this happens, we can use more
targeted help message.

Closes #21390
Closes #21600

265a23320d Auto merge of #21677 - japaric:no-range, r=alexcrichton 
Note: Do not merge until we get a newer snapshot that includes #21374

There was some type inference fallout (see 4th commit) because type inference with `a..b` is not as good as with `range(a, b)` (see #21672).

09783d1dab Update test files; mostly the problem is that they were using the 
explicit form `Fn<A,B>` and now should use `Fn(A) -> B` or
`Fn<A,Output=B>`, but in some cases we get duplicate error
reports. This is mildly annoying and arises because of the main error
and another error from the projection. Might be worth squashing those,
but seems like a separate problem.

07cdb85331 Move return type an associated type of the Fn* traits. Mostly this involves tweaking things in 
the compiler that assumed two input types to assume two ouputs; we also have to teach `project.rs`
to project `Output` from the unboxed closure and fn traits.
