[debuginfo] Make debuginfo type names for slices and str consistent.

2022-10-31T14:43:44+00:00

Before this PR, the compiler would emit the debuginfo name `slice$` for all kinds of slices, regardless of whether they are behind a reference or not and regardless of the kind of reference. As a consequence, the types `Foo<&[T]>`, `Foo<[T]>`, and `Foo<&mut [T]>` would end up with the same type name `Foo >` in debuginfo, making it impossible to disambiguate between them by name. Similarly, `&str` would get the name `str` in debuginfo, so the debuginfo name for `Foo` and `Foo<&str>` would be the same. In contrast, `*const [bool]` and `*mut [bool]` would be `ptr_const$ >` and `ptr_mut$ >`, i.e. the encoding does not lose information about the type. This PR removes all special handling for slices and `str`. The types `&[bool]`, `&mut [bool]`, and `&str` thus get the names `ref$ >`, `ref_mut$ >`, and `ref$` respectively -- as one would expect.

Remove byte swap of valtree hash on big endian

2022-10-19T06:55:33+00:00

Use enum2<_> instead of enum<_> for Cpp-like debuginfo enum type names.

2022-08-12T08:53:07+00:00

And add more comments about niche tag enum encoding.

debuginfo: Change C++-like encoding for enums.

2022-08-12T08:53:07+00:00

The updated encoding should be able to handle niche layouts where more than one variant has fields.

Allow to create definitions inside the query system.

Rename the `ConstS::val` field as `kind`.

2022-06-14T03:06:44+00:00

And likewise for the `Const::val` method. Because its type is called `ConstKind`. Also `val` is a confusing name because `ConstKind` is an enum with seven variants, one of which is called `Value`. Also, this gives consistency with `TyS` and `PredicateS` which have `kind` fields. The commit also renames a few `Const` variables from `val` to `c`, to avoid confusion with the `ConstKind::Value` variant.

Remove NodeIdHashingMode.
