2f8f256cef require the existential bounds of an object type to be object-safe
This is required, as Copy and Sized are object-unsafe.

As a soundness fix, this is a [breaking-change]

Fixes #32963

0a6dfc5177 require the non-last elements of a tuple to be Sized
This requirement appears to be missing from RFC1214, but is clearly
necessary for translation. The last field of a tuple/enum remains in
a state of limbo, compiling but causing an ICE when it is used - we
should eventually fix that somehow.

this is a [breaking-change] - a soundness fix - and requires a
crater run.

73f39a026a Short-cut Sized matching on ADTs
Put a constraint type on every ADT def, such that the ADT def is sized iff the constraint
type is, and use that in selection. This ignores types that are obviously sized.

This improves typeck performance by ~15%.

f6019760f9 Rollup merge of #32596 - soltanmm:lazy, r=nikomatsakis
Plumb obligations through librustc/infer

Like #32542, but more like #31867.

TODO before merge: make an issue for the propagation of obligations through... uh, everywhere... then replace the `#????`s with the actual issue number.
