Add a test checking the output of builtin derives.

// edition:2021
//
// This test checks the code generated for all[*] the builtin derivable traits
// on a variety of structs and enums. It protects against accidental changes to
// the generated code, and makes deliberate changes to the generated code
// easier to review.
//
// [*] It excludes `Copy` in some cases, because that changes the code
// generated for `Clone`.
//
// [*] It excludes `RustcEncodable` and `RustDecodable`, which are obsolete and
// also require the `rustc_serialize` crate.

Don't use match-destructuring for derived ops on structs. All derive ops currently use match-destructuring to access fields. This is reasonable for enums, but sub-optimal for structs. E.g.: ``` fn eq(&self, other: &Point) -> bool { match *other { Self { x: ref __self_1_0, y: ref __self_1_1 } => match *self { Self { x: ref __self_0_0, y: ref __self_0_1 } => (*__self_0_0) == (*__self_1_0) && (*__self_0_1) == (*__self_1_1), }, } } ``` This commit changes derive ops on structs to use field access instead, e.g.: ``` fn eq(&self, other: &Point) -> bool { self.x == other.x && self.y == other.y } ``` This is faster to compile, results in smaller binaries, and is simpler to generate. Unfortunately, we have to keep the old pattern generating code around for `repr(packed)` structs because something like `&self.x` (which doesn't show up in `PartialEq` ops, but does show up in `Debug` and `Hash` ops) isn't allowed. But this commit at least changes those cases to use let-destructuring instead of match-destructuring, e.g.: ``` fn hash<__H: ::core::hash::Hasher>(&self, state: &mut __H) -> () { { let Self(ref __self_0_0) = *self; { ::core::hash::Hash::hash(&(*__self_0_0), state) } } } ``` There are some unnecessary blocks remaining in the generated code, but I will fix them in a follow-up PR.

Don't use match-destructuring for derived ops on structs. All derive ops currently use match-destructuring to access fields. This is reasonable for enums, but sub-optimal for structs. E.g.: ``` fn eq(&self, other: &Point) -> bool { match *other { Self { x: ref __self_1_0, y: ref __self_1_1 } => match *self { Self { x: ref __self_0_0, y: ref __self_0_1 } => (*__self_0_0) == (*__self_1_0) && (*__self_0_1) == (*__self_1_1), }, } } ``` This commit changes derive ops on structs to use field access instead, e.g.: ``` fn eq(&self, other: &Point) -> bool { self.x == other.x && self.y == other.y } ``` This is faster to compile, results in smaller binaries, and is simpler to generate. Unfortunately, we have to keep the old pattern generating code around for `repr(packed)` structs because something like `&self.x` (which doesn't show up in `PartialEq` ops, but does show up in `Debug` and `Hash` ops) isn't allowed. But this commit at least changes those cases to use let-destructuring instead of match-destructuring, e.g.: ``` fn hash<__H: ::core::hash::Hasher>(&self, state: &mut __H) -> () { { let Self(ref __self_0_0) = *self; { ::core::hash::Hash::hash(&(*__self_0_0), state) } } } ``` There are some unnecessary blocks remaining in the generated code, but I will fix them in a follow-up PR.

Avoid the unnecessary innermost match in `partial_cmp`/`cmp`. We currently do a match on the comparison of every field in a struct or enum variant. But the last field has a degenerate match like this: ``` match ::core::cmp::Ord::cmp(&self.y, &other.y) { ::core::cmp::Ordering::Equal => ::core::cmp::Ordering::Equal, cmp => cmp, }, ``` This commit changes it to this: ``` ::core::cmp::Ord::cmp(&self.y, &other.y), ``` This is fairly straightforward thanks to the existing `cs_fold1` function. The commit also removes the `cs_fold` function which is no longer used. (Note: there is some repetition now in `cs_cmp` and `cs_partial_cmp`. I will remove that in a follow-up PR.)

Don't use match-destructuring for derived ops on structs. All derive ops currently use match-destructuring to access fields. This is reasonable for enums, but sub-optimal for structs. E.g.: ``` fn eq(&self, other: &Point) -> bool { match *other { Self { x: ref __self_1_0, y: ref __self_1_1 } => match *self { Self { x: ref __self_0_0, y: ref __self_0_1 } => (*__self_0_0) == (*__self_1_0) && (*__self_0_1) == (*__self_1_1), }, } } ``` This commit changes derive ops on structs to use field access instead, e.g.: ``` fn eq(&self, other: &Point) -> bool { self.x == other.x && self.y == other.y } ``` This is faster to compile, results in smaller binaries, and is simpler to generate. Unfortunately, we have to keep the old pattern generating code around for `repr(packed)` structs because something like `&self.x` (which doesn't show up in `PartialEq` ops, but does show up in `Debug` and `Hash` ops) isn't allowed. But this commit at least changes those cases to use let-destructuring instead of match-destructuring, e.g.: ``` fn hash<__H: ::core::hash::Hasher>(&self, state: &mut __H) -> () { { let Self(ref __self_0_0) = *self; { ::core::hash::Hash::hash(&(*__self_0_0), state) } } } ``` There are some unnecessary blocks remaining in the generated code, but I will fix them in a follow-up PR.

Don't use match-destructuring for derived ops on structs. All derive ops currently use match-destructuring to access fields. This is reasonable for enums, but sub-optimal for structs. E.g.: ``` fn eq(&self, other: &Point) -> bool { match *other { Self { x: ref __self_1_0, y: ref __self_1_1 } => match *self { Self { x: ref __self_0_0, y: ref __self_0_1 } => (*__self_0_0) == (*__self_1_0) && (*__self_0_1) == (*__self_1_1), }, } } ``` This commit changes derive ops on structs to use field access instead, e.g.: ``` fn eq(&self, other: &Point) -> bool { self.x == other.x && self.y == other.y } ``` This is faster to compile, results in smaller binaries, and is simpler to generate.

Don't use match-destructuring for derived ops on structs. All derive ops currently use match-destructuring to access fields. This is reasonable for enums, but sub-optimal for structs. E.g.: ``` fn eq(&self, other: &Point) -> bool { match *other { Self { x: ref __self_1_0, y: ref __self_1_1 } => match *self { Self { x: ref __self_0_0, y: ref __self_0_1 } => (*__self_0_0) == (*__self_1_0) && (*__self_0_1) == (*__self_1_1), }, } } ``` This commit changes derive ops on structs to use field access instead, e.g.: ``` fn eq(&self, other: &Point) -> bool { self.x == other.x && self.y == other.y } ``` This is faster to compile, results in smaller binaries, and is simpler to generate. Unfortunately, we have to keep the old pattern generating code around for `repr(packed)` structs because something like `&self.x` (which doesn't show up in `PartialEq` ops, but does show up in `Debug` and `Hash` ops) isn't allowed. But this commit at least changes those cases to use let-destructuring instead of match-destructuring, e.g.: ``` fn hash<__H: ::core::hash::Hasher>(&self, state: &mut __H) -> () { { let Self(ref __self_0_0) = *self; { ::core::hash::Hash::hash(&(*__self_0_0), state) } } } ``` There are some unnecessary blocks remaining in the generated code, but I will fix them in a follow-up PR.
