…ons vs callers

… a consistent way

Remove `Word` from the `unix_sigpipe` attribute template so that plain `#[unix_sigpipe]` is not included in suggestions of valid forms of the attribute. Also re-arrange diagnostics code slightly to avoid duplicate diagnostics.

Fixes rust-lang#122234

io::Read trait: make it more clear when we are adressing implementations vs callers Inspired by [this](rust-lang#72186 (comment)) comment. For some reason we only have that `buf` warning in `read` and `read_exact`, even though it affects a bunch of other functions of this trait as well. It doesn't seem worth copy-pasting the same text everywhere though so I did not change this.

BorrowedCursor docs clarification If one reads the `BorrowedCursor` docs without having seen `BorrowedBuf` before, it is quite easy to assume that "unfilled" and "uninit" are synonyms.

use Instance::expect_resolve() instead of unwraping Instance::resolve()

…errors MIR printing: print the path of uneval'd const Currently it just prints `const _` which makes it impossible to say which constant is being referred to. Also refer to promoteds in a consistent way; previously MIR printing would do ``` promoted[0] in C1: &Option<Cell<i32>> = { // ... } ``` Now that should be ``` const C1::promoted[0]: &Option<Cell<i32>> = { // ... } ``` We don't seem to have a test for that so I tried it by hand, it seems to work: ``` const main::promoted[12]: &[&str; 3] = { let mut _0: &[&str; 3]; let mut _1: [&str; 3]; let mut _2: &str; let mut _3: &str; let mut _4: &str; let mut _5: &str; bb0: { _3 = const "b"; _2 = &(*_3); _5 = const "c"; _4 = &(*_5); _1 = [const "a", move _2, move _4]; _0 = &_1; return; } } ```

…ease diagnostics: Do not suggest using `#[unix_sigpipe]` without a value Remove `Word` from the `unix_sigpipe` attribute template so that plain `#[unix_sigpipe]` is not included in suggestions of valid forms of the attribute. Also re-arrange diagnostics code slightly to avoid duplicate diagnostics. Tracking issue is rust-lang#97889.

…zkan bootstrap: document what the triples in 'Build' mean Thanks to ``@onur-ozkan`` for pointing this out to me.

docs: Correct ptr/ref verbiage in SliceIndex docs. Fixes rust-lang#122234

…er-errors fix metadata for dyn-star in new solver The pointee metadata of `dyn* Trait` types is `()` and not a vtable.
