1. Fix rustc version when clippy-driver is used …

   This is a combined cherry-pick of the following two commits:
   
   - 18b8da9 ("Handle rustc version output correctly...")
   - cdf12d2 ("Update `rustc_version_cmd`")
   
   These two commits are squashed for the backport to slightly reduce the
   amount of conflict resolution needed going forward (some small tweaks
   were still needed).
   
   This backports the following:
   
   - <rust-lang#3893>
   - <rust-lang#3903>
   
   Commit 1 original message:
   
       Handle rustc version output correctly when `clippy-driver` used
   
   Commit 2 original message:
   
       Update `rustc_version_cmd`
   
       Change `if let` to a `match` because it is about the same complexity but
       also works with our MSRV for 0.2. This should allow backporting [1]
       easier, as well as future backports that touch this code.
   
       Additionally, add some new documentation comments.

2. Simplify the RUSTC_WRAPPER check …

   This should be compatible with older versions of rustc, to get the
   branches more in sync.
