Adjust Miri value visitor, and doc-comment layout components I realized that I still didn't have quite the right intuition for how our `LayoutDetails` work, so I had to adjust the Miri value visitor to the things I understood better now. I also added some doc-comments to `LayoutDetails` as a hopefully canonical place to note such things. The main visitor change is that we *first* look at all the fields (according to `FieldPlacement`), and *then* check the variants and handle `Multiple` appropriately. I did not quite realize how orthogonal "fields" and "variants" are. I also moved the check for the scalar ABI to *after* checking all the fields; this leads to better (more type-driven) error messages. And it looks like we can finally remove that magic hack for `ty::Generator`. :D r? @oli-obk for the Miri/visitor changes and @eddyb for the layout docs The Miri PR is at: rust-lang/miri#1178
