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?
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.
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.
@jseyfried @sanxiyn
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.
Fixes#33992
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.
