The goal here is to avoid writing to the `inherent_impls` map from
within the general `Coherence` task, and instead write to it as we
visit. Writing to it from the Coherence task is actually an information
leak; it happened to be safe because Coherence read from
`DepNode::Krate`, but that was very coarse.
I removed the `Rc` here because, upon manual inspection, nobody clones
the data in this table, and it meant that we can accumulate the data in
place. That said, the pattern that is used for the inherent impls map
is *generally* an anti-pattern (that is, holding the borrow lock for the
duration of using the contents), so it'd probably be better to
clone (and I doubt that would be expensive -- how many inherent impls
does a typical type have?).
rustdoc: Fix associated consts in search results
Associated consts can appear in none trait impls so need to be treated
like methods when generating the search index.
Fixes#36031
Fix issue #36036.
Fix#36036.
We were treating an associated type as unsized even when the concrete instantiation was actually sized. Fix is to normalize before checking if it is sized.
Fix incorrect LLVM Linkage enum
Followup of #33994 to actually work.
The `Linkage` enum in librustc_llvm got out of sync with the version in LLVM and it caused two variants of the `#[linkage=""]` attribute to break.
This adds the functions `LLVMRustGetLinkage` and `LLVMRustSetLinkage` which convert between the Rust Linkage enum and the LLVM one, which should stop this from breaking every time LLVM changes it.
Possible remaining concerns:
1. There could be a codegen test to make sure that the attributes are applied correctly (I don't know how to do this).
2. ~~The test does not exercise the `appending` linkage. I can't figure out how to make a global static raw pointer to an array. This might not even be possible? If not we should probably remove appending linkage as its unusable in rust.~~ Appending linkage is not 'emittable' anyway.
3. The test only runs on Linux.
Fixes#33992

Typecheck refactor for `!`
Ping @nikomatsakis @eddyb. This is the PR for the typeck refactor for `!`. Is this what you guys had in mind? Is there anything else that needs doing on it?

Use libraries from local-rust-root directory in configure when using …
…--enable-local-rebuild
When using --enable-local-rebuild configure options, the configure
script will test rustc version. But when running it, it will not use the
libraries in the local-rust-root directory.
So use `LD_LIBRARY_PATH` environment variable to correct it.
Under OpenBSD, we use `--enable-local-rebuild` for rebuilding rustc-1.11.0 using rustc-1.11.0. But as it is in use in -current (the developpment branch of OpenBSD), system libraries could easily have ABI/API changes. The (unofficial) bootstrap (rustc-1.11.0 used for building rustc-1.11.0) include several system libraries to permit it to run. The build system use libraries in stage0/lib directory. But the configure script doesn't.
Due to my special use of `--enable-local-rebuild`, I dunno if this PR is suitable for inclusion. But it corrects a difference between build and configure use of the binary.

Allow CompilerControllers to access rustc_plugin::registry::Registry
fixes#36064
I chose to put ructc_plugin::registry::Registry structure
into CompilerState structure, instead of Session structure.
This will preserve dependencies among librustc, libructc_driver, and libructc_plugin.

Replace `_, _` with `..` in patterns
This is how https://github.com/rust-lang/rust/issues/33627 looks in action.
Looks especially nice in leftmost/rightmost positions `(first, ..)`/`(.., last)`.
I haven't touched libsyntax intentionally because the feature is still unstable.
rustbuild: add config.toml option to disable codegen tests
Fixes#36232.
I think it worked? Here's a build log where I tried to bootstrap, it crashed, then I added the setting to config.toml and it continued: https://gist.github.com/durka/cbf97cf04b8e065f1a2cfda4c1b6bf95

Update nightly docs supported Windows versions to match Getting Started page
https://doc.rust-lang.org/book/getting-started.html#tier-1 shows that Windows 7+ is officially supported (implying, for example Windows 10), but the nightly page only listed 7, 8, and Server 2008 R2).
Updated e0493 to new format (+ bonus).
Part of #35233.
Fixes#35999.
r? @jonathandturner
I'm not satisfied with the bonus part, there has to be an easier way to reach into the `Drop`'s span implementation. I'm all ears. :)
Add --Zsave-analysis-api
This is a save-analysis variation which can be used with libraries distributed without their source (e.g., libstd). It will allow IDEs and other tools to get info about types and create URLs to docs and source, without the unnecessary clutter of internal-only save-analysis info. I'm sure we'll iterate somewhat on the design, but this is a first draft.
