4abb455529 Update ty::VariantDef to use IndexVec<FieldIdx, FieldDef> 
And while doing the updates for that, also uses `FieldIdx` in `ProjectionKind::Field` and `TypeckResults::field_indices`.

There's more places that could use it (like `rustc_const_eval` and `LayoutS`), but I tried to keep this PR from exploding to *even more* places.

cf073ec2cb Auto merge of #109202 - compiler-errors:new-solver-fast-reject-faster-2, r=lcnr 
Don't pass `TreatProjections` separately to `fast_reject`

Don't pass `TreatProjections` separately to `fast_reject`, and instead use the original approach of switching on two variants of `TreatParams` (undoes this: https://github.com/rust-lang/rust/pull/108830#pullrequestreview-1330371417).

Fixes the regression introduced in https://github.com/rust-lang/rust/pull/108830#issuecomment-1468116419

Rollup merge of #107718 - Zoxc:z-time, r=nnethercote 
Add `-Z time-passes-format` to allow specifying a JSON output for `-Z time-passes`

This adds back the `-Z time` option as that is useful for [my rustc benchmark tool](https://github.com/Zoxc/rcb), reverting https://github.com/rust-lang/rust/pull/102725. It now uses nanoseconds and bytes as the units so it is renamed to `time-precise`.

9bdb4881c7 Auto merge of #109119 - lcnr:trait-system-cleanup, r=compiler-errors 
a general type system cleanup

removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.

changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.

also removes some other small - and imo unnecessary - helpers.

diagnostics: if AssocFn has self argument, describe as method

Discussed in https://rust-lang.zulipchat.com/#narrow/stream/147480-t-compiler.2Fwg-diagnostics/topic/.22associated.20function.22.20vs.20.22method.22/near/329265515

This commit also changes the tooltips on rustdoc intra-doc links targeting methods.

For anyone not sure why this is being done, see the Reference definitions of these terms in <https://doc.rust-lang.org/1.67.1/reference/items/associated-items.html#methods>

> Associated functions whose first parameter is named `self` are called methods and may be invoked using the [method call operator](https://doc.rust-lang.org/1.67.1/reference/expressions/method-call-expr.html), for example, `x.foo()`, as well as the usual function call notation.

In particular, while this means it's technically correct for rustc to refer to a method as an associated function (and there are a few cases where it'll still do so), rustc *must never* use the term "method" to refer to an associated function that does not have a `self` parameter.
