Make `x test --stage 2 compiler/rustc_XXX` faster to run

Previously, bootstrap unconditionally rebuilt the stage 2 compiler,
even if it had previously built stage 1. This changes it to reuse stage 1 if possible.
In particular, it no longer runs the following step:
```
Building stage1 compiler artifacts (x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu) -> x86_64-unknown-linux-gnu(x86_64-unknown-linux-gnu))
```
