… error

rewrite using let-chains

Signed-off-by: Jonathan Brouwer <jonathantbrouwer@gmail.com>

…rrors Merge unboxed trait object error suggestion into regular dyn incompat error Another hir-walker removed from the well-formed queries. This error was always a duplicate of another, but it was able to provide more information because it could invoke `is_dyn_compatible` without worrying about cycle errors. That's also the reason we can't put the error directly into hir_ty_lowering when lowering a `dyn Trait` within an associated item signature. So instead I packed it into the error handling of wf obligation checking.

…ange, r=compiler-errors Add a warning to LateContext::get_def_path Preventing anyone from doing the same error as rust-lang/rust-clippy#15043 fixed

Add DesugaringKind::FormatLiteral Implements `DesugaringKind::FormatLiteral` to mark the FormatArgs desugaring of format literals. The main use for this is to stop yapping about about formatting parameters if we're not anywhere near a format literal. The other use case is to fix suggestions such as rust-lang#141350. It might also be useful for new or existing diagnostics that check whether they're in a format-like macro. cc `@xizheyin` `@fmease`

…aring, r=fee1-dead Clean-up `FnCtxt::is_destruct_assignment_desugaring` I noticed the docstring thing and fixed that; then I thought I'd rewrite the method using let-chains while I'm at it, since that seemed appropriate. But I don't feel too strongly about the second change, so let me know if I should remove it

… r=jdonszelmann Port `#[must_use]` to new attribute parsing infrastructure Ports `must_use` to the new attribute parsing infrastructure for rust-lang#131229 (comment) r? `@jdonszelmann`

…r-errors Don't fail to parse a struct if a semicolon is used to separate fields The first commit is a small refactor.

…chenkov Add a few inline directives in rustc_serialize. I see `debug_strict_add` and `debug_strict_sub` appearing in callgrind output. This bothers me. This PR should make them disappear.

remove few allow(dead_code) Few from serial/parallel compiler leftovers and few from bootstrap.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
