Auto merge of #42527 - qnighy:unsized-tuple-coercions, r=arielb1
Unsized tuple coercions Part of #18469. Fixes #32702. #37685 and #34451 might also be related. This PR does the following: - Introduce explicit `Sized` constraints on tuple initializers, similar to that of record-struct initializers. Not much relevant to the main contribution but I noticed this when making tests for unsized tuple coercions. - Implement `(.., T): Unsize<(.., U)>` where `T: Unsize<U>`. - Assume `(.., T)` is MaybeUnsizedUnivariant. - Modify `src/librustc/ty/util.rs` and `src/librustc_trans/glue.rs` so that tuples and structs are uniformly traversed when translating.
