Rollup merge of #104338 - compiler-errors:pointer-sized, r=eholk
Enforce that `dyn*` coercions are actually pointer-sized Implement a perma-unstable, rudimentary `PointerSized` trait to enforce `dyn*` casts are `usize`-sized for now, at least to prevent ICEs and weird codegen issues from cropping up after monomorphization since currently we enforce *nothing*. This probably can/should be removed in favor of a more sophisticated trait for handling `dyn*` conversions when we decide on one, but I just want to get something up for discussion and experimentation for now. r? ```@eholk``` cc ```@tmandry``` (though feel free to claim/reassign) Fixes #102141 Fixes #102173
