@jonorossi, I'd appreciate your input on one particular detail here. In principle, this PR is an extension of #619, whose code patterns it duplicates for the most part. After this PR, the |

(The type name `DerivedEmptyGenericRecord` suggests that it is generic, which is not the case; `DerivedFromEmptyGenericRecord` is more accurate. For consistency, let's apply the same name change to `EmptyRecord` and its subtype.)

Performing this check for anything other than return types is basically wasted time, so moving it to `EqualReturnTypes` means it will only run when actually needed.

Fixes #632.
It turns out that we only added support for non-generic covariant return types in #619; however there are two additional cases that we need to support, too:
(I'm counting those as two distinct cases due to the code structure found inside
MethodSignatureComparer.EqualSignatureTypes, which is the method that needs to be augmented.)
