Use delay_span_bug instead of panic in layout_scalar_valid_range #83054 introduced validation of scalar range attributes, but panicking code that uses the attribute remained reachable. Use `delay_span_bug` instead to avoid the ICE. Fixes #83180.

pnkfelix:bootstrap-tell-me-what-to-do-about-tidy-on-beta, r=Mark-Simulacrum More informative diagnotic from `x.py test` attempt atop beta checkout Make bootstrap be more informative when one does `x.py test` on a beta checkout without other mods. To be clear, by default running `x.py test` on a checkout of the beta branch currently fails, and with this change will continue to fail, because `x.py tests` runs `x.py test src/tools/tidy` which tries to run `rustfmt` and that will fail because the `rustfmt` binary is pinned to the current nighlty and we do not attempt to distribute one for the beta builds. This change gives a better error message than the current message, which is just "./x.py fmt is not supported on this channel" without providing any hint about what one might do about that problem.

Specify *.woff2 files as binary This prevents older git versions to change the "line endings". Fixes #83159.

2021-03-16Rollup merge of #83156 - nagisa:nagisa/sans-serif-please, r=GuillaumeGomezYuki Okushi-4/+5
Fall-back to sans-serif if Arial is not available Otherwise on systems where Arial is not available the UA will fallback to a serif font, rather than a sans-serif one. This is especially relevant on acessibility-conscious setups (such as is mine) that have web-fonts disabled and a limited set of fonts available on the system. r? ```@GuillaumeGomez``` cc ```@jsha```

2021-03-16Rollup merge of #81822 - Kixunil:path_try_exists, r=kennytmYuki Okushi-0/+30
Added `try_exists()` method to `std::path::Path` This method is similar to the existing `exists()` method, except it doesn't silently ignore the errors, leading to less error-prone code. This change intentionally does NOT touch the documentation of `exists()` nor recommend people to use this method while it's unstable. Such changes are reserved for stabilization to prevent confusing people. Apart from that it avoids conflicts with #80979. `@joshtriplett` requested this PR in [internals discussion](https://internals.rust-lang.org/t/the-api-of-path-exists-encourages-broken-code/13817/25?u=kixunil)

2021-03-16Auto merge of #82898 - oli-obk:tait_🧊, r=nikomatsakisbors-686/+5447
Add a `min_type_alias_impl_trait` feature gate This new feature gate only permits type alias impl trait to be constrained by function and trait method return types. All other possible constraining sites like const/static types, closure return types and binding types are now forbidden and gated under the `type_alias_impl_trait` and `impl_trait_in_bindings` feature gates (which are both marked as incomplete, as they have various ways to ICE the compiler or cause query cycles where they shouldn't). r? `@nikomatsakis` This is best reviewed commit-by-commit

2021-03-15Rollup merge of #83132 - Aaron1011:fix/incr-cache-dummy, r=estebankDylan DPC-3/+29
Don't encode file information for span with a dummy location Fixes #83112 The location information for a dummy span isn't real, so don't encode it. This brings the incr comp cache code into line with the Span `StableHash` impl, which doesn't hash the location information for dummy spans. Previously, we would attempt to load the 'original' file from a dummy span - if the file id changed (e.g. due to being moved on disk), we would get an ICE, since the Span was still valid due to its hash being unchanged.
2021-03-15Rollup merge of #83127 - Aaron1011:time-macros-impl-warn, r=petrochenkovDylan DPC-65/+206
Introduce `proc_macro_back_compat` lint, and emit for `time-macros-impl` Now that future-incompat-report support has landed in nightly Cargo, we can start to make progress towards removing the various proc-macro back-compat hacks that have accumulated in the compiler. This PR introduces a new lint `proc_macro_back_compat`, which results in a future-incompat-report entry being generated. All proc-macro back-compat warnings will be grouped under this lint. Note that this lint will never actually become a hard error - instead, we will remove the special cases for various macros, which will cause older versions of those crates to emit some other error. I've added code to fire this lint for the `time-macros-impl` case. This is the easiest case out of all of our current back-compat hacks - the crate was renamed to `time-macros`, so seeing a filename with `time-macros-impl` guarantees that an older version of the parent `time` crate is in use. When Cargo's future-incompat-report feature gets stabilized, affected users will start to see future-incompat warnings when they build their crates.
