this improves typeck performance by 5% (LLVM times are still huge).
Basically fixes #25916 (still O(n^2), but the example takes <1s to
compile).

# FIXME #11094 - The above rule doesn't work right for multiple targets

(Notice that unlike the `println!` macro we’ve used in the past, we use square
-brackets `[]` with `vec!` macro. Rust allows you to use either in either situation,
-this is just convention.)
+brackets `[]` with `vec!` macro. Rust allows you to use either in either
+situation, this is just convention.)
There’s an alternate form of `vec!` for repeating an initial value:
let v = vec![0; 10]; // ten zeroes
```
+Vectors store their contents as contiguous arrays of `T` on the heap. This means
+that they must be able to know the size of `T` at compile time (that is, how
+many bytes are needed to store a `T`?). The size of some things can't be known
+at compile time. For these you'll have to store a pointer to that thing:
+thankfully, the [`Box`][box] type works perfectly for this.
+
## Accessing elements
To get the value at a particular index in the vector, we use `[]`s:
API documentation][vec].
