This currently has no effect, but is expected to be useful when expanding
support for branch coverage and MC/DC coverage.

Remove `#[macro_use] extern crate rustc middle` from numerous crates

Because explicit importing of macros via `use` items is nicer (more standard and readable) than implicit importing via `#[macro_use]`. This PR mops up some cases I didn't get to in #124511.

4497d345a8 Remove extern crate rustc_middle from rustc_const_eval.
This requires exporting the interpreter macros so they can be used with
`use crate::interpret::*`.

Rename some `FulfillmentErrorCode`/`ObligationCauseCode` variants to be less redundant

1. Rename some `FulfillmentErrorCode` variants.
2. Always use `ObligationCauseCode::` to prefix a code, rather than using a glob import and naming them through `traits::`.
3. Rename some `ObligationCauseCode` variants -- I wasn't particularly thorough with thinking of a new names for these, so could workshop them if necessary.
4. Misc stuff from renaming.

Rollup merge of #124797 - beetrees:primitive-float, r=davidtwco
Refactor float `Primitive`s to a separate `Float` type

Now there are 4 of them, it makes sense to refactor `F16`, `F32`, `F64` and `F128` out of `Primitive` and into a separate `Float` type (like integers already are). This allows patterns like `F16 | F32 | F64 | F128` to be simplified into `Float(_)`, and is consistent with `ty::FloatTy`.

As a side effect, this PR also makes the `Ty::primitive_size` method work with `f16` and `f128`.

62318b38ef fix: Check whether next_node is else-less if in get_return_block
Fix #124819, where a if-less block causes a wrong output. It is
caused by get_return_block in get_fn_decl. In get_return_block,
when a else-less if expression is the tail expression, the check
for next_node will keep iterating. So it is necessary to make a
early return in the check.

f5d7d346a4 Remove TinyList.
It is optimized for lists with a single element, avoiding the need for
an allocation in that case. But `SmallVec<[T; 1]>` also avoids the
allocation, and is better in general: more standard, log2 number of
allocations if the list exceeds one item, and a much more capable API.

This commit removes `TinyList` and converts the two uses to
`SmallVec<[T; 1]>`. It also reorders the `use` items in the relevant
file so they are in just two sections (`pub` and non-`pub`), ordered
alphabetically, instead of many sections. (This is a relevant part of
the change because I had to decide where to add a `use` item for
`SmallVec`.)

Handle normalization failure in `struct_tail_erasing_lifetimes`

Fixes #113272

The ICE occurred because the struct being normalized had an error. This PR adds some defensive code to guard against that.

never patterns: lower never patterns to `Unreachable` in MIR

This lowers a `!` pattern to "goto Unreachable". Ideally I'd like to read from the place to make it clear that the UB is coming from an invalid value, but that's tricky so I'm leaving it for later.
