rustdoc: Fix a couple of issues with src links to external crates
- src links/redirects to extern fn from another crate had an extra '/'.
- src links to `pub use` of a crate module had an extra '/'.
- src links to renamed reexports from another crate used the new name
for the link but should use the original name.
Fixes: #34274
configure: Remove clang version checks
We no C++ and an incredibly small amount of C code as part of the build, so
there's not really much need for us to strictly check the version of compilers
as we're not really stressing anything. LLVM is a pretty huge chunk of C++ but
it should be the responsibility of LLVM to ensure that it can build with a
particular clang/gcc version, not ours (as this logic changes over time).
These version checks seem to basically just by us a regular stream of PRs every
six weeks or so when a new version is releases, so they're not really buying us
much. As a result, remove them and we can add then back piecemeal perhaps as a
blacklist if we really need to.
Fix overflow error in thread::sleep
Fixes#34330
I added a test to have a more clear error inside the function. Since `time_t` is `i64` and we expect `u64`, maybe we should changed the awaited type?
Add custom message parameter to `assert_eq!`
`assert!` macro accepts a custom message parameter and it's sometimes useful. But `assert_eq!` doesn't have it and users need to use `assert!` instead of `assert_eq!` when they want to output a custom message even if the assertion just compares two values. This pull request will resolve those cases.
Improves organization of driver includes.
Minor reordering of use's in librustc_driver/driver.rs
- puts her::lower::lower_create with it's siblings
- groups link and write of rustc_trans::back
book: Fixed links in book/compiler-plugins.md
Updated the links referring to roman_numerals.rs and lint_plugin_test.rs. Went from src/test/auxiliary/ to src/test/run-pass-fulldeps/auxiliary/.
Remove unzip() SizeHint hack
This was using an invalid iterator so is likely to end with buggy
behaviour.
It also doesn't even benefit many type in std including Vec so removing it
shouldn't cause any problems.
Fixes: #33468
trans: generalize immediate temporaries to all MIR locals.
Added `Mir::local_index` which gives you an unified index for `Arg`, `Var`, `Temp` and `ReturnPointer`.
Also available is `Mir::count_locals` which returns the total number of the above locals.
This simplifies a lot of the code which can treat all of the local lvalues in the same manner.
If we had `-> impl Iterator`, I could have added a bunch of useful `Ty` or `Lvalue` iterators for all locals.
We could of course manually write such iterators as they are needed.
The only place which currently takes advantage of unified locals is trans' alloca elision.
Currently it's not as good as it could be, due to our usage of `llvm.dbg.declare` in debug mode.
But passing some arguments and variables as immediates has some effect on release-mode `libsyntax`:

Implementation of #34168

I only updated `librustc_privacy/diagnostics.rs`, and I already found a case where the code doesn't throw the expected error code (E0448).
Fixes#34168.
