Divergence here means that for some reason, the end of a block will not be
reached. We tried to model this just using the never type, but that doesn't work
fully (e.g. in `let x = { loop {}; "foo" };` x should still have type `&str`);
so this introduces a `diverges` flag that the type checker keeps track of, like
rustc does.
4376: Fix type of byte literals r=matklad a=flodiebold
They're `&[u8; N]`, not `&[u8]` (see #4374).

4329: Look for `cargo`, `rustc`, and `rustup` in standard installation path r=matklad a=cdisselkoen
Discussed in #3118. This is approximately a 90% fix for the issue described there.
This PR creates a new crate `ra_env` with a function `get_path_for_executable()`; see docs there. `get_path_for_executable()` improves and generalizes the function `cargo_binary()` which was previously duplicated in the `ra_project_model` and `ra_flycheck` crates. (Both of those crates now depend on the new `ra_env` crate.) The new function checks (e.g.) `$CARGO` and `$PATH`, but also falls back on `~/.cargo/bin` manually before erroring out. This should allow most users to not have to worry about setting the `$CARGO` or `$PATH` variables for VSCode, which can be difficult e.g. on macOS as discussed in #3118.
I've attempted to replace all calls to `cargo`, `rustc`, and `rustup` in rust-analyzer with appropriate invocations of `get_path_for_executable()`; I don't think I've missed any in Rust code, but there is at least one invocation in TypeScript code which I haven't fixed. (I'm not sure whether it's affected by the same problem or not.) https://github.com/rust-analyzer/rust-analyzer/blob/a4778ddb7a00f552a8e653bbf56ae9fd69cfe1d3/editors/code/src/cargo.ts#L79
I'm sure this PR could be improved a bunch, so I'm happy to take feedback/suggestions on how to solve this problem better, or just bikeshedding variable/function/crate names etc.

4346: Fix rename of enum variant visible from module r=matklad a=montekki
Probably fixes#4237
It looks like the ref is found correctly in this case but it's visibility is not correctly determined. I took a stab at fixing that by adding an implementation of `HasVisibility` for `EnumVariant` so it works more or less the same way it does for struct fields.
In other words, the `search_range` here does not contain the ref since it's not considered visible:
https://github.com/rust-analyzer/rust-analyzer/blob/efd8e34c396f1524623a495e47111f1047cf2879/crates/ra_ide_db/src/search.rs#L209-L214
Before that I tried to populate `ItemScope` with visible enum variants but that ended up with breaking tests all over the place and also it looked illogical in the end: `ItemScope` is not populated with, say, public struct fields and the same should be true for `enum` variants.
I've added two more or less identical tests: one for the case with a struct field rename and one for enum variant rename; the test for struct should probably be removed and the names should be changed.
