make miri-seed a regular integer, and also set layout-seed in many-seeds
This makes the seed format consistent between `-Zlayout-seed` and `-Zmiri-seed`.
try_normalize_after_erasing_regions: promote an assertion to always run
In https://github.com/rust-lang/miri/issues/2433 this assertion has been seen to trigger, so it might be worth actually checking this? Regressing debug assertions are very easy to miss until much later, and then they become quite hard to debug.
Don't duplicate last cdb debuginfo test command
cdb scripts interpret a blank line to mean "repeat the last command", similar to what happens when running the debugger from a console. The code for compiletest that constructs the debugger script was inserting a blank line between the last command and the "quit" command. This caused the last command to be executed twice. This can cause some confusion since the `-check` lines are expecting the output in a certain order. But printing the last command twice causes that order-assumption to fail, and that can cause confusion.
This fixes it by removing the blank line.
AFAICT, gdb and lldb scripts don't have the same behavior with blank lines (and the gdb code doesn't add any blank lines anyways).
* Fix doc examples for Platforms with underaligned integer primitives.
* Mutable pointer doc examples use mutable pointers.
* Fill out tracking issue.
* Minor formatting changes.

Improve spans for RPITIT object-safety errors
No reason why we can't point at the `impl Trait` that causes the object-safety violation.
Also [drive-by: Add is_async fn to hir::IsAsync](c4165f3a96), which touches clippy too.

Don't focus on notable trait parent when hiding it
I clicked on a notable trait icon so the popup remained and then clicked on the settings menu. When the settings menu was blurred, it scrolled back to when the notable trait was, which isn't great.

Make "long type" printing type aware and trim types in E0275
Instead of simple string cutting, use a custom printer to hide parts of long printed types.
On E0275, check for type length before printing.
fix sysroot issue which appears for ci downloaded rustc
Currently when compiler is downloaded rather than compiled, sysroot is being `ci-rustc-sysroot` because of 7eef946fc0/src/bootstrap/compile.rs (L1125-L1131) this.
And rustdoc is overriding the downloaded one at the end of the process.
With the condition I add, we simply check if the current compiler stage is target build stage, if so use the proper sysroot instead of `ci-rustc-sysroot`.
Resolves#103206
Fix build of std for thumbv7a-pc-windows-msvc
Attempting to build std for the tier-3 target `thumbv7a-pc-windows-msvc` fails with the following error:
```
Building stage1 std artifacts (x86_64-pc-windows-msvc -> thumbv7a-pc-windows-msvc)
..
LLVM ERROR: WinEH not implemented for this target
error: could not compile `panic_unwind`
```
EH (unwinding) is not supported by LLVM for 32 bit arm msvc targets. This changes panic unwind to use the dummy implementation for `thumbv7a-pc-windows-msvc`.
Partial support for running UI tests with `download-rustc`
Right now trying to run UI tests with `download-rustc` results in a bunch of test failures, requiring someone who wants to only work on tests to also build the full compiler. This PR **partially** addresses the problem by solving a lot of the errors (but not all).
* This installs the `rust-src` component on CI toolchains, since the test output depends on whether the standard library source code is installed; We can't just symlink the current source because the `rustc-dev` component already includes the compiler sources, but not the library sources, and mixing things is worse IMO.
* This ensures the `$SRC_DIR` normalization done by compiletest correctly handles the source code added above.
* This unconditionally sets `remap-prefix` to the prefix used in the downloaded toolchain, to ensure compiletest normalizes it.
Use `IsTerminal` in place of `atty`
In any crate that can use nightly features, use `IsTerminal` rather than
`atty`:
- Use `IsTerminal` in `rustc_errors`
- Use `IsTerminal` in `rustc_driver`
- Use `IsTerminal` in `rustc_log`
- Use `IsTerminal` in `librustdoc`
Revert Vec/Rc storage reuse opt
Remove the optimization for using storage added by #104205.
The perf wins were pretty small, and it relies on non-guarenteed behaviour. On platforms that don't implement shrinking in place, the performance will be significantly worse.
While it could be gated to platforms that do this (such as GNU), I don't think it's worth the overhead of maintaining it for very small gains. (#104565, #104563)
