Refactor `get_first_two_components` to `get_next_component`. Fixes the following behaviour of `parse_prefix`: - series of separator bytes in a prefix are correctly parsed as a single separator - device namespace prefixes correctly recognize both `\\` and `/` as separators
gsgdt [https://crates.io/crates/gsgdt] is a crate which provides an interface for stringly typed graphs. It also provides generation of graphviz dot format from said graph.

Move intrinsics lowering pass from the optimization phase (where it would not run if -Zmir-opt-level=0), to the drop lowering phase where it runs unconditionally. The implementation of those intrinsics in code generation and interpreter is unnecessary. Remove it.
make MIR graphviz generation use gsgdt gsgdt [https://crates.io/crates/gsgdt] is a crate which provides an interface for stringly typed graphs. It also provides generation of graphviz dot format from said graph. This is the first in a series of PRs on moving graphviz code out of rustc into normal crates and then implementating graph diffing on top of these crates. r? `@oli-obk`
Refactor and fix `parse_prefix` on Windows This PR is an extension of rust-lang#78692 as well as a general refactor of `parse_prefix`: **Fixes**: There are two errors in the current implementation of `parse_prefix`: Firstly, in the current implementation only `\` is recognized as a separator character in device namespace prefixes. This behavior is only correct for verbatim paths; `"\\.\C:/foo"` should be parsed as `"C:"` instead of `"C:/foo"`. Secondly, the current implementation only handles single separator characters. In non-verbatim paths a series of separator characters should be recognized as a single boundary, e.g. the UNC path `"\\localhost\\\\\\C$\foo"` should be parsed as `"\\localhost\\\\\\C$"` and then `UNC(server: "localhost", share: "C$")`, but currently it is not parsed at all, because it starts being parsed as `\\localhost\` and then has an invalid empty share location. Paths like `"\\.\C:/foo"` and `"\\localhost\\\\\\C$\foo"` are valid on Windows, they are equivalent to just `"C:\foo"`. **Refactoring**: All uses of `&[u8]` within `parse_prefix` are extracted to helper functions and`&OsStr` is used instead. This reduces the number of places unsafe is used: - `get_first_two_components` is adapted to the more general `parse_next_component` and used in more places - code for parsing drive prefixes is extracted to `parse_drive`
Remove memoization leftovers from constant evaluation machine Closes rust-lang#79667
…ikomatsakis Move binder for dyn to each list item This essentially changes `ty::Binder<&'tcx List<ExistentialTraitRef>>` to `&'tcx List<ty::Binder<ExistentialTraitRef>>`. This is a first step in moving the `dyn Trait` representation closer to Chalk, which we've talked about in `@rust-lang/wg-traits.` r? `@nikomatsakis`

Fix overflow when converting ZST Vec to VecDeque
```rust
let v = vec![(); 100];
let queue = VecDeque::from(v);
println!("{:?}", queue);
```
This code will currently panic with a capacity overflow.
This PR resolves this issue and makes the code run fine.
