7b0eaef580 Implement type inference for more binary operators
Mostly just for primitive numeric types such as u32 and f64. Not
yet a general solution using trait resolution.

cf49a11263 Sort ranges in type inference tests
Also rename the files to remove the numbers (they don't serve a purpose now that
there are only the data files).

6210e82041 Use HIR Expr for type inference
Now we can reuse the type inference inside a function when typing whitespace
etc. :)

440: Implement type inference for boolean operators r=flodiebold a=marcusklaas

Tried implementing the easiest part of https://github.com/rust-analyzer/rust-analyzer/issues/390. Hope this is somewhat close to what the intent of the issue was. Found it surprisingly easy to find my way around the repository - it's well organized!

Very grateful for any pointers.

82d9a77dad Touch up type inference for boolean operators
Also try to infer its subexpressions and set type expectations
whenever possible.

a6f33b4ca5 Add test for invalidation of inferred types when typing inside function
This currently fails, but should work once we have hir::Expr.

cfa1de72eb Implement type variables
This will really become necessary when we implement generics, but even now, it
allows us to reason 'backwards' to infer types of expressions that we didn't
understand for some reason.

We use ena, the union-find implementation extracted from rustc, to keep track of
type variables.
