Part of rust-lang#47319. This just adds type parameter name to type mismatch error message, so e.g. the following: ``` expected enum `std::option::Option`, found type parameter ``` becomes ``` expected enum `std::option::Option`, found type parameter `T` ```
Fixes rust-lang#47319. Shows the type parameter definition(s) on type mismatch errors so the context is clearer. Pretty much changes the following: ``` LL | bar1(t); | ^ | | | expected enum `std::option::Option`, found type parameter `T` ``` into: ``` LL | fn foo1<T>(t: T) { | - this type parameter LL | bar1(t); | ^ | | | expected enum `std::option::Option`, found type parameter `T` ```
Update the tests to reflect changes to how type mismatch errors are reported (two previous commits).
Type parameters are referenced in the error message after the previous few commits (using span label). But when the main error message already references the very same type parameter it becomes clumsy. Do not show the additional label in this case as per code review comment by @estebank. Also this contains a small style fix.

When `break;` has a type mismatch because the `Destination` points at a tail expression with an obligation flowing from a return type, point at the return type. Fix rust-lang#39968.

…tion, r=estebank Show type parameter name and definition in type mismatch error messages Fixes rust-lang#47319 r? estebank
…, r=alexcrichton Move has_panic_handler to query Moves us off of a global Once instead re-querying the lang item each time. The conditions on when we set it to true change a little (previously we'd make sure a few more lang items were `Some`) but I think they in practice don't matter, we won't compile later on if we don't have them.
syntax: Avoid span arithmetic for delimiter tokens The +/-1 logic is from the time where the whole group had a single span and the delimiter spans had to be calculated from it. Now the delimiters have their own spans which are constructed by lexer or proc macro API and can be used directly. If those spans are not perfect, then it should be fixed by tweaking the corresponding lexer logic rather than by trying to add or substract `1` from the span boundaries.
