chalkify: Implement lowering rule Implied-Bound-From-Trait
For #49177.
TODO:
- [x] Implement where clauses besides trait and projection predicates
- [x] Is the output of the `lower_trait_higher_rank` test correct?
- [ ] Remove `Self::Trait` from the query `tcx.predicates_of(<trait_id>).predicates`
- [ ] Consider moving tests to compile-fail to make them more manageable
std: Be sure to modify atomics in tests
See #49775 for some more information but it looks like this is working around an
LLVM bug for the time being.
Closes#49775
In issue #49588, Michael Lamparski pointed out a scenario in which the
non-shorthand-field-patterns lint could be triggered by a macro-expanded
pattern, in a way which was direly unwieldy for the macro author to guard
against and unreasonable to expect the macro user to take into account. We can
avoid this by not linting patterns that come from macro-expansions. Although
this entails accepting "false negatives" where the lint could genuinely improve
macro-templated code, avoiding the reported "true-but-super-annoying positive"
may be worth the trade? (Some precedent for these relative priorities exists as
no. 47775 (5985b0b0).)
Resolves#49588.
Impressing confused Python users with magical diagnostics is perhaps
worth this not-grossly-unreasonable (only 40ish lines) extra complexity
in the parser?
Thanks to Vadim Petrochenkov for guidance.
This resolves#46836.

r? @Mark-Simulacrum
Correct a few stability attributes
* `const_indexing` language feature was stabilized in 1.26.0 by #46882
* `Display` impls for `PanicInfo` and `Location` were stabilized in 1.26.0 by #47687
* `TrustedLen` is still unstable so its impls should be as well even though `RangeInclusive` was stabilized by #47813
* `!Send` and `!Sync` for `Args` and `ArgsOs` were stabilized in 1.26.0 by #48005
* `EscapeDefault` has been stable since 1.0.0 so should continue to show that even though it was moved to core in #48735
This could be backported to beta like #49612
