This gives us an extra rustc-src.tar.xz, which is 33% smaller than the .tar.gz!
This commit adds a new `-Z` flag to the compiler for use when bootstrapping the compiler itself. We want to be able to use crates.io crates, but we also want the usage of such crates to be as ergonomic as possible! To that end compiler crates are a little tricky in that the crates.io crates are not annotated as unstable, nor do they expect to pull in unstable dependencies. To cover all these situations it's intended that the compiler will forever now bootstrap with `-Z force-unstable-if-unmarked`. This flags serves a dual purpose of forcing crates.io crates to themselves be unstable while also allowing them to use other "unstable" crates.io crates. This should mean that adding a dependency to compiler no longer requires upstream modification with unstable/staged_api attributes for inclusion!
There's no shell interpreting the file paths under the new Rusty rust-installer, so we don't need to use `sanitize_sh` for it. Plus, the drive-letter transformation is actually harmful for the now-native Windows rust-installer to understand those paths.
These are now no longer necessary with `-Z force-unstable-if-unmarked`
Removes unused macros from:
* libcore
* libcollections
The last use of these two macros was removed in commit
b64c9d5
when the char_range_at_reverse function was been removed.
* librustc_errors
Their last use was removed by commits
2f2c3e1
and 11dc974.
* libsyntax_ext
* librustc_trans
Also, put the otry macro in back/msvc/mod.rs under the
same cfg argument as the places that use it.
This seems both to be a safe, conservative choice, and it sidesteps the cycle in rust-lang#41936. Fixes rust-lang#41936.
This fix an issue where the compiler panics even if there is no error when passed with the `-Z treat-err-as-bug` option. Fixes rust-lang#35886.
…richton Update to the Rusty rust-installer This updates the rust-installer submodule to the new version written in Rust (rust-lang/rust-installer#62), now moved to `src/tools/rust-installer` and invoked in `dist.rs` as a cargo-based tool command. All of the former shell-script invocations now invoke the tool, otherwise keeping the same arguments as before. As a small bonus, `rustc-src` now also uses the same tarball generator, so it gains a smaller `.tar.xz` too. Fixes rust-lang#41569. r? @alexcrichton

rustc_trans: do not attempt to truncate an i1 const to i1. Fixes rust-lang#41744 by skipping the truncation when it'd be a noop anyway.
Remove unused macros from the codebase Thanks to the lint I've implemented in rust-lang#41907 I've found some unused macros inside the rustc codebase.
…oerce-unsized-cycle, r=eddyb use equality in the coerce-unsized check This seems both to be a safe, conservative choice, and it sidesteps the cycle in rust-lang#41849. Note that, before I converted variance into proper queries, we were using a hybrid of subtyping and equality, due to the presence of a flag that forced invariance if variance had not yet been computed. (Also, Coerce Unsized is unstable.) Fixes rust-lang#41936. r? @eddyb
