2020-09-02pretty: trim paths of unique symbolsDan Aloni-18/+18
If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not.

Better error note on unimplemented Index trait for string fixes #56740 I've tried to compile suggestion from comments in the issue #56740, but unsure of it. So I'm open to advice :) Current output will be like this: ```rust error[E0277]: the type `str` cannot be indexed by `{integer}` --> $DIR/str-idx.rs:3:17 | LL | let c: u8 = s[4]; //~ ERROR the type `str` cannot be indexed by `{integer}` | ^^^^ `str` cannot be indexed by `{integer}` | = help: the trait `std::ops::Index<{integer}>` is not implemented for `str` = note: you can use `.chars().nth()` or `.bytes().nth()` see chapter in The Book <https://doc.rust-lang.org/book/ch08-02-strings.html#indexing-into-strings> error: aborting due to previous error For more information about this error, try `rustc --explain E0277`. ``` `x.py test src/test/ui` succeeded and I've also tested output manually by compiling the following code: ```rust fn _f() { let s = std::string::String::from("hello"); let _c = s[0]; let s = std::string::String::from("hello"); let mut _c = s[0]; let s = "hello"; let _c = s[0]; let s = "hello"; let mut _c = &s[0]; } ``` Not sure if some docs should be changed too. I will also fix error message in the [Book :: Indexing into Strings](https://github.com/rust-lang/book/blob/db53e2e3cdf77beac853df6f29db4b3b86ea598c/src/ch08-02-strings.md#indexing-into-strings) if that PR will get approved :)
