When failing to parse struct-like enum variants, the ADT gets recorded
as having no fields. Record that we have actually recovered during
parsing of this variant to avoid complaing about non-existing fields
when actually using it.
overhaul intra-doc-link ambiguity warning
Fixes#52784.
- Makes the warning part of the `intra_doc_link_resolution_failure`
lint.
- Tightens the span to just the ambiguous link.
- Reports ambiguities across all three namespaces.
- Uses structured suggestions for disambiguation.
- Adds a test for the warnings.

Filter ui revision tests
Updates UI test output filtering to also filter away test annotations for revisions:
Previously filtered: //~ ERROR [XXXX]
Now also filters: //[revision]~ ERROR [XXXX]
I reckon, if we have the one, we should have the other for consistency, its lack was probably an oversight (the existence of revision testing is not really well documented...)
`src/ci/docker`, so that when files under `dist-x86_64-linux` is changed,
its dependent image `dist-i686-linux` will also be rebuilt.
However, this ultraconservative solution caused the `dist-i686-linux` to
be rebuilt every time an irrelevant Dockerfile (e.g. the PowerPC ones) is
changed, which increases the building time beyond 3 hours and forcing
a spurious but expected failure.
This commit instead parses the Dockerfile itself and look for the actual
dependencies. The scripts needs to be copied into the Docker image, which
must be done with the COPY command, so we just need to find all lines with
a COPY command and add the source file into the hash calculator.
Note: this script only handles single-lined COPY command in the form
`COPY src1 src2 src3 dst`, since these are the only variant used inside
this repository.
Revert the `LazyConst` PR
The introduction of `LazyConst` did not actually achieve the code simplicity improvements that were the main reason it was introduced. Especially in the presence of const generics, the differences between the "levels of evaluatedness" of a constant become less clear. As it can be seen by the changes in this PR, further simplifications were possible by folding `LazyConst` back into `ConstValue`. We have been able to keep all the advantages gained during the `LazyConst` refactoring (like `const_eval` not returning an interned value, thus making all the `match` code simpler and more performant).

Do not accidentally treat multi-segment meta-items as single-segment
Fixes https://github.com/rust-lang/rust/issues/55168 and many other regressions from https://github.com/rust-lang/rust/pull/50030
Basically, attributes like `#[any::prefix::foo]` were commonly interpreted as `#[foo]` due to `name()` successfully returning the last segment (this applies to nested things as well `#[attr(any::prefix::foo)]`).
This should make it easier to identify what each job is doing when looking at the Travis or Appveyor UI.
- Set `name` for each job in Travis.
- Move `CI_JOB_NAME` to the front in Appveyor so that it appears first in the UI.
