Since September, the toolchain has not been generating reliable DWARF information for static variables when LTO is on. This has affected projects in the embedded space where the use of LTO is typical. In our case, it has kept us from bumping past the 2021-09-22 nightly toolchain lest our debugger break. This has been a pretty dramatic regression for people using debuggers and static variables. See rust-lang#90357 for more info and a repro case. This commit is a mechanical revert of d5de680 from PR rust-lang#89041, which caused the issue. (Note on that PR that the commit's author has requested it be reverted.) I have locally verified that this fixes rust-lang#90357 by restoring the functionality of both the repro case I posted on that bug, and debugger behavior on real programs. There do not appear to be test cases for this in the toolchain; if I've missed them, point me at 'em and I'll update them.
- Re-enabled basic-types-globals which has been disabled since 2018 - Updated its now-rotted assertions about GDB's output to pass - Rewrote header comment describing some previous state of GDB behavior that didn't match either the checked-in assertions _or_ the current behavior, and so I assume has just been wrong for some time. - Copy-pasta'd the test into a version that uses LTO to check for regression on rust-lang#90357, because I don't see a way to matrix the same test into several build configurations.
The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.

…pnkfelix Only add codegen backend to dep info if -Zbinary-dep-depinfo is used I am currently migrating the cg_clif build system from using a binary linked to the codegen backend as rustc replacement to passing `-Zcodegen-backend` instead. Without this PR this would force cargo to rebuild the sysroot on any change to the codegen backend even if I explicitly specify that I want it to be preserved, which would make development of cg_clif a lot slower. If you still want to have changes to the codegen backend invalidate the cargo build cache you can explicitly specify `-Zbinary-dep-depinfo`. cc `````@eddyb````` as the codegen backend was initially added to the depinfo for rust-gpu.
Add missing links in platform support docs I was looking at m68k support and saw that https://doc.rust-lang.org/rustc/platform-support.html and the sidebar there were missing some links to target documentation
Parse inner attributes on inline const block According to rust-lang#84414 (comment), inner attributes are intended to be supported *"in all containers for statements (or some subset of statements)"*. This PR adds inner attribute parsing and pretty-printing for inline const blocks (rust-lang#76001), which contain statements just like an unsafe block or a loop body. ```rust let _ = const { #![allow(...)] let x = (); x }; ```

…ubilee implement SIMD gather/scatter via vector getelementptr Fixes rust-lang/portable-simd#271 However, I don't *really* know what I am doing here... Cc `@workingjubilee` `@calebzulawski` I didn't do anything for cranelift -- `@bjorn3` not sure if it's okay for that backend to temporarily break. I'm happy to cherry-pick a patch that adds cranelift support. :)
