Constify most non-trait `Duration` methods as described in #72440
The remaining methods could probably be made const once https://github.com/rust-lang/rust/pull/72449 lands with support for `f<32|64>::is_finite()`.
Update reference to CONTRIBUTING.md
CONTRIBUTING.md has been migrated to the rustc-dev-guide but some still refer there.

Fixes#74253
Handle case of incomplete local ty more gracefully
When encountering a local binding with a type that isn't completed, the
parser will reach a `=` token. When this happen, consider the type
"complete" as far as the parser is concerned to avoid further errors
being emitted by parse recovery logic.
improve DiscriminantKind handling
Adds a lang item `discriminant_type` for the associated type `DiscriminantKind::Discriminant`.
Changes the discriminant of generators from `i32` to `u32`, which should not be observable to fix an
oversight where MIR was using `u32` and codegen and typeck used `i32`.
This now reuses `fn discriminant_ty` in project, removing
some code duplication. Doing so made me realize that
we previously had a disagreement about the discriminant
type of generators, with MIR using `u32` and codegen and
trait selection using `i32`.
We now always use `u32`.

Note that the output of `unpretty-debug.stdout` has changed. In that
test the hash values are normalized from a symbol numbers to small
numbers like "0#0" and "0#1". The increase in the number of static
symbols must have caused the original numbers to contain more digits,
resulting in different pretty-printing prior to normalization.
lint: use `transparent_newtype_field` to avoid ICE
Fixes#73747.
This PR re-uses the `transparent_newtype_field` function instead of manually calling `is_zst` on normalized fields to determine which field in a transparent type is the non-zero-sized field, thus avoiding an ICE.
typeck: use `item_name` in cross-crate packed diag
Fixes#73112.
This PR replaces the use of `expect_local` and `hir().get` to fetch the identifier for a ADT with `item_name` - which works across crates.

When encountering a unit or tuple pattern for a struct-like item, suggest
using the correct pattern.
Use `insert_field_names_local` when evaluating variants and store field
names even when the list is empty in order to produce accurate
structured suggestions.

typeck: report placeholder type error w/out span
Fixes#74086.
This PR fixes a regression introduced in rust-lang/rust#70369 which meant that an error was not being emitted for invalid placeholder types when there wasn't a span available.

typeck: check for infer before type impls trait
Fixes#73886.
This PR checks that the target type of the cast (an error related to which is being reported) does not have types to be inferred before checking if it implements the `From` trait.
