9307917d6a Adds language to the documentation for Option and Result suggesting 
the use of lazily evaluated alternatives when appropriate. These
comments are intended to echo a clippy lint on the same topic (see

061bdb5c12 Auto merge of #46524 - eddyb:static-static, r=arielb1 
rustc_mir: promote references of statics from other statics.

Fixes #46522 by also allowing `STATIC_REF` in MIR const-qualification, not just AST rvalue promotion.

5a2465e2b4 Auto merge of #45953 - estebank:tab-4, r=nikomatsakis 
Display `\t` in diagnostics code as four spaces

Follow up to #44386 using the unicode variable width machinery from #45711 to replace tabs in the source code when displaying a diagnostic error with four spaces (instead of only one), while properly accounting for this when calculating underlines.

Partly addresses #44618.

Give compile_error macro examples

I cannot get Rust to build at all with it complaining about GCC not being a valid C compiler or something, so letting TravisCI be my tester...

Update old link

The CONTRIBUTING.md page currently links to an old wiki page in rust-lang/rust-wiki-backup. There is a more up-to-date page in-tree so I changed the link to point there so new contributors can find it more easily.

Mention the name of ? in Result's docs

Fixes #42725

or at least, this is the best we can really do. #35946 is tracking
better errors already, so that should cover the other part of it.

632ad19135 Auto merge of #46192 - arielb1:locally-coherent, r=nikomatsakis 
coherence: fix is_knowable logic

A trait-ref that passes the orphan-check rules can still be implemented in a crate downstream from our crate (for example, `LocalType for LocalTrait<_>` might be matched by a `LocalType for LocalTrait<TypeFromDownstreamCrate>`), and this should be known by the `is_knowable`  logic.

Trait selection had a hackfix for this, but it's an hacky fix that does not handle all cases. This patch removes it.

fixes #43355.
