fix few typos in filecheck annotations
Inspired by https://github.com/rust-lang/rust/pull/123886#discussion_r1597358732
`rg -g '*.rs' '//\s+?[\w-]+(-[\w]+):' -r '$1' -oNI | sort -u`
Should https://llvm.org/docs/CommandGuide/FileCheck.html#cmdoption-FileCheck-ignore-case be used for case-insensetive match for filecheck?

Handle Deref expressions in invalid_reference_casting
Similar to https://github.com/rust-lang/rust/pull/124908
See https://github.com/rust-lang/rust/issues/124951 for context; this PR fixes the last of the known false postiive cases with this lint that we encounter in Crater.

check if `x test tests` missing any test directory
Add a unit test to ensure we don't skip any test directories for `x test tests` in the future.

Document proper usage of `fmt::Error` and `fmt()`'s `Result`.
I've seen several newcomers wonder why `fmt::Error` doesn't have any error detail information, or propose to return it in response to an error condition found inside a `impl fmt::Display for MyType`.
That is incorrect, per [a lone paragraph of the `fmt` module's documentation](https://doc.rust-lang.org/1.78.0/std/fmt/index.html#formatting-traits). However, users looking to implement a formatting trait won't necessarily look there. Therefore, let's add the critical information (that formatting per se is infallible) to all the involved items: every `fmt()` method, and `fmt::Error`.
This PR is not intended to make any novel claims about `fmt`; only to repeat an existing one in places where it will be more visible.

Refactor Apple `target_abi`
This was bundled together with `Arch`, which complicated a few code paths and meant we had to do more string matching than necessary.
CC `@BlackHoleFox` as you've worked on the Apple target spec before
Related: Is there a reason why `Target`/`TargetOptions` use `StaticCow` for so many things, instead of an enum with defined values (and perhaps a catch-all case for custom target json files)? Tagging `@Nilstrieb,` as you might know?

Make sure we consume a generic arg when checking mistyped turbofish
When recovering un-turbofish-ed args in expr position (e.g. `let x = a<T, U>();` in `check_mistyped_turbofish_with_multiple_type_params`, we used `parse_seq_to_before_end` to parse the fake generic args; however, it used `parse_generic_arg` which *optionally* parses a generic arg. If it doesn't end up parsing an arg, it returns `Ok(None)` and consumes no tokens. If we don't find a delimiter after this (`,`), we try parsing *another* element. In this case, we just infinitely loop looking for a subsequent element.
We can fix this by making sure that we either parse a generic arg or error in `parse_seq_to_before_end`'s callback.
Fixes #124897

reachable computation: extend explanation of what this does, and why
Follow-up to https://github.com/rust-lang/rust/pull/122769. I had the time to think about this some more, in particular in the context of https://github.com/rust-lang/rust/issues/119214, so I felt it was worth extending these comments some more.
I also gave up on the context of "externally reachable" as it is not called that way anywhere else in the compiler.

Add `-lmingwex` second time in `mingw_libs`
Upcoming mingw-w64 releases will contain small math functions refactor which moved implementation around. As a result functions like `lgamma`
now depend on libraries in this order:
`libmingwex.a` -> `libmsvcrt.a` -> `libmingwex.a`.

Avoid `alloca`s in codegen for simple `mir::Aggregate` statements
The core idea here is to remove the abstraction penalty of simple newtypes in codegen.
Even something simple like constructing a
```rust
#[repr(transparent)] struct Foo(u32);
```
forces an `alloca` to be generated in nightly right now.
Certainly LLVM can optimize that away, but it would be nice if it didn't have to.
Quick example:
```rust
#[repr(transparent)]
pub struct Transparent32(u32);
#[no_mangle]
pub fn make_transparent(x: u32) -> Transparent32 {
let a = Transparent32(x);
a
}
```
on nightly we produce <https://rust.godbolt.org/z/zcvoM79ae>
```llvm
define noundef i32 `@make_transparent(i32` noundef %x) unnamed_addr #0 {
%a = alloca i32, align 4
store i32 %x, ptr %a, align 4
%0 = load i32, ptr %a, align 4, !noundef !3
ret i32 %0
}
```
but after this PR we produce
```llvm
define noundef i32 `@make_transparent(i32` noundef %x) unnamed_addr #0 {
start:
ret i32 %x
}
```
(even before the optimizer runs).

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.
