Toolstate: Don't block beta week on already broken tools. This changes it so that tools are allowed to be broken entering the beta week if they are already broken. This restores the original behavior before the changes in #69332. Closes #68458

Unrevert "Remove `checked_add` in `Layout::repeat`" This reapplies @kraai's original `libcore::alloc::Layout::repeat` change from #67174 which was temporarily reverted in #69241. Now that the proper LLVM fix has been cherry-picked, we can unrevert the revert. This change was originally reviewed by @hanna-kruppe on the initial PR. cc @RalfJung

2020-03-02Auto merge of #69257 - RalfJung:layout-visitor, r=eddybbors-203/+238
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: https://github.com/rust-lang/miri/pull/1178

rustc_metadata: Load metadata for indirect macro-only dependencies Imagine this dependency chain between crates ``` Executable crate -> Library crate -> Macro crate ``` where "Library crate" uses the macros from "Macro crate" for some code generation, but doesn't reexport them any further. Currently, when compiling "Executable crate" we don't even load metadata for it, because why would we want to load any metadata from "Macro crate" if it already did all its code generation job when compiling "Library crate". Right? Wrong! Hygiene data and spans (https://github.com/rust-lang/rust/issues/68686, https://github.com/rust-lang/rust/pull/68941) from "Macro crate" still may need to be decoded from "Executable crate". So we'll have to load them properly. Questions: - How this will affect compile times for larger crate trees in practice? How to measure it? Hygiene/span encoding/decoding will necessarily slow down compilation because right now we just don't do some work that we should do, but this introduces a whole new way to slow down things. E.g. loading metadata for `syn` (and its dependencies) when compiling your executable if one of its library dependencies uses it. - We are currently detecting whether a crate reexports macros from "Macro crate" or not, could we similarly detect whether a crate "reexports spans" and keep it unloaded if it doesn't? Or at least "reexports important spans" affecting hygiene, we can probably lose spans that only affect diagnostics.
