Miscellaneous changes for CI, Docker and compiletest.
This PR contains 7 independent commits that improves interaction with CI, Docker and compiletest.
1. a4e5c91cb8 — Forces a newline every 100 dots when testing in quiet mode. Prevents spurious timeouts when abusing the CI to test Android jobs.
2. 1b5aaf22e8 — Use vault.centos.org for dist-powerpc64le-linux, see #45744.
3. 33400fbbcd — Modify `src/ci/docker/run.sh` so that the docker images can be run from Docker Toolbox for Windows on Windows 7. I haven't checked the behavior of the newer Docker for Windows on Windows 10. Also, "can run" does not mean all the test can pass successfully (the UDP tests failed last time I checked)
4. d517668a08 — Don't emit a real warning the linker segfault, which affects UI tests like https://github.com/rust-lang/rust/pull/45489#issuecomment-340134944. Log it instead.
5. 51e2247948 — During run-pass, trim the output if stdout/stderr exceeds 416 KB (top 160 KB + bottom 256 KB). This is an attempt to avoid spurious failures like https://github.com/rust-lang/rust/pull/45384#issuecomment-341755788
6. 9cfdabaf3c — Force `gem update --system` before deploy. This is an attempt to prevent spurious error #44159.
7. eee10cc482 — Tries to print the crash log on macOS on failure. This is an attempt to debug #45230.
incr.comp.: Verify stability of incr. comp. hashes and clean up various other things.
The main contribution of this PR is that it adds the `-Z incremental-verify-ich` functionality. Normally, when the red-green tracking system determines that a certain query result has not changed, it does not re-compute the incr. comp. hash (ICH) for that query result because that hash is already known. `-Z incremental-verify-ich` tells the compiler to re-hash the query result and compare the new hash against the cached hash. This is a rather thorough way of
- testing hashing implementation stability,
- finding missing `[input]` annotations on `DepNodes`, and
- finding missing read-edges,
since both a missed read and a missing `[input]` annotation can lead to something being marked as green instead of red and thus will have a different hash than it should have.
Case in point, implementing this verification logic and activating it for all `src/test/incremental` tests has revealed several such oversights, all of which are fixed in this PR.

tools: Fix rustfmt and the RLS
These tools have been corrected in their upstream repo's, and the submodules have been updated here to reflect that. I also had to update Cargo to match what the RLS is expecting.
The tool states for `rustfmt` and `rls` where both changed from "Broken" to "Testing" in this commit, thus enabling testing and distribution again.

again.
This is intended to prevent the spurious OOM error from
run-pass/rustc-rust-log.rs, by skipping the output in the middle when the
size is over 416 KB, so that the log output will not be overwhelmed.
Copy all `AsciiExt` methods to the primitive types directly in order to deprecate it later
**EDIT:** [this PR is ready now](https://github.com/rust-lang/rust/pull/44042#issuecomment-333883548). I edited this post to reflect the current status of discussion, which is (apart from code review) pretty much settled.
---
This is my current progress in order to prepare stabilization of #39658. As discussed there (and in #39659), the idea is to deprecated `AsciiExt` and copy all methods to the type directly. Apparently there isn't really a reason to have those methods in an extension trait¹.
~~This is **work in progress**: copy&pasting code while slightly modifying the documentation isn't the most exciting thing to do. Therefore I wanted to already open this WIP PR after doing basically 1/4 of the job (copying methods to `&[u8]`, `char` and `&str` is still missing) to get some feedback before I continue. Some questions possibly worth discussing:~~
1. ~~Does everyone agree that deprecating `AsciiExt` is a good idea? Does everyone agree with the goal of this PR?~~ => apparently yes
2. ~~Are my changes OK so far? Did I do something wrong?~~
3. ~~The issue of the unstable-attribute is currently set to 0. I would wait until you say "Ok" to the whole thing, then create a tracking issue and then insert the correct issue id. Is that ok?~~
4. ~~I tweaked `eq_ignore_ascii_case()`: it now takes the argument `other: u8` instead of `other: &u8`. The latter was enforced by the trait. Since we're not bound to a trait anymore, we can drop the reference, ok?~~ => I reverted this, because the interface has to match the `AsciiExt` interface exactly.
¹ ~~Could it be that we can't write `impl [u8] {}`? This might be the reason for `AsciiExt`. If that is the case: is there a good reason we can't write such an impl block? What can we do instead?~~ => we couldn't at the time this PR was opened, but Simon made it possible.

Otherwise changes to the compiler are unable to introduce new
warnings: some crates tested by cargotest deny all warnings and
thus, the CI build fails.
Thanks SimonSapin for the patch!
Shorten paths to auxiliary files created by tests
I'm hitting issues with long file paths to object files created by the test suite, similar to https://github.com/rust-lang/rust/issues/45103#issuecomment-335622075.
If we look at the object file path in https://github.com/rust-lang/rust/issues/45103 we can see that the patch contains of few components:
```
specialization-cross-crate-defaults.stage2-x86_64-pc-windows-gnu.run-pass.libaux\specialization_cross_crate_defaults.specialization_cross_crate_defaults0.rust-cgu.o
```
=>
1. specialization-cross-crate-defaults // test name, required
2. stage2 // stage disambiguator, required
3. x86_64-pc-windows-gnu // target disambiguator, required
4. run-pass // mode disambiguator, rarely required
5. libaux // suffix, can be shortened
6. specialization_cross_crate_defaults // required, there may be several libraries in the directory
7. specialization_cross_crate_defaults0 // codegen unit name, can be shortened?
8. rust-cgu // suffix, can be shortened?
9. o // object file extension
This patch addresses items `4`, `5` and `8`.
`libaux` is shortened to `aux`, `rust-cgu` is shortened to `rcgu`, mode disambiguator is omitted unless it's necessary (for pretty-printing and debuginfo tests, see https://github.com/rust-lang/rust/pull/24537/commits/38d26d811a44ba93637c84ce77a58af88c47f0ac)
I haven't touched names of codegen units though (`specialization_cross_crate_defaults0`).
Is it useful for them to have descriptive names including the crate name, as opposed to just `0` or `cgu0` or something?
enable non-lexical lifetimes in the MIR borrow checker
This PR, joint work with @spastorino, fills out the NLL infrastructure and integrates it with the borrow checker. **Don't get too excited:** it includes still a number of hacks (the subtyping code is particularly hacky). However, it *does* kinda' work. =)
The final commit demonstrates this by including a test that -- with both the AST borrowck and MIR borrowck -- reports an error by default. But if you pass `-Znll`, you only get an error from the AST borrowck, demonstrating that the integration succeeds:
```
struct MyStruct {
field: String
}
fn main() {
let mut my_struct = MyStruct { field: format!("Hello") };
let value = &my_struct.field;
if value.is_empty() {
my_struct.field.push_str("Hello, world!");
//~^ ERROR cannot borrow (Ast)
}
}
```
Bump to 1.23 and update bootstrap
This commit updates the bootstrap compiler, bumps the version to 1.23, updates
Cargo, updates books, and updates crates.io dependencies
Update rls-data for save analysis
rls-data: 0.10 -> 0.11
This will allow for more fine-grained save analysis for enum variants (tuple and struct).
The first commit updates rls-data, and makes the changes to dump_visitor. The second commit updates the rls submodule, and removes "members" that were deleted from that update in src/Cargo.toml.
Note, that when building the project, rustfmt-nightly was updated in Cargo.lock. If these changes should be excluded, I can revert it.

Add Stylo and WebRender to src/tools/cargotest
This is a subset of Servo that takes relatively less time to compile and does not use unstable Rust features.
Move Generics from MethodSig to TraitItem and ImplItem
As part of `rust-impl-period/WG-compiler-traits`, we want to "lift" `Generics` from `MethodSig` into `TraitItem` and `ImplItem`. This is in preparation for adding associated type generics. (https://github.com/rust-lang/rust/issues/44265#issuecomment-331172238)
Currently this change is only made in the AST. In the future, it may also impact the HIR. (Still discussing)
To understand this PR, it's probably best to start from the changes to `ast.rs` and then work your way to the other files to understand the far reaching effects of this change.
