By performing this logic very late in the build process, it ended up leading to
bugs like those found in #10973 where certain stages of the build process
expected a particular output format which didn't end up being the case. In order
to fix this, the build output generation is moved very early in the build
process to the absolute first thing in phase 2.

Closes #10973

[`get_unwrap`]: include a borrow in the suggestion if argument is not an integer literal

Fixes rust-lang#9909

I have to say, I don't really understand what the previous logic was trying to do, but this fixes the linked bug.
It was checking if the argument passed to `.get()` can be parsed as a usize (i.e. if it's an integer literal, probably?), and if not, it wouldn't include a borrow? I don't know how we came to that conclusion, but that logic doesn't work:
```rs
let slice = &[1, 2];
let _r: &i32 = slice.get({ 1 }).unwrap();
// previous suggestion: slice[{ 1 }]
// the suggestion should be: &slice[{ 1 }]
```
Here the argument passed to it isn't an integer literal, but it should still include a borrow, because it would otherwise change the type from `&i32` to `i32`.

The exception is that if the parent of the `get().unwrap()` expr is a dereference or a method call or the like, we don't need an explicit borrow because it's automatically inserted by the compiler
