IR: minor refactoring in FakeOverrideRebuilder

Browse Source 
Extract the common logic of remapping fake overrides into a function.

Also, slightly change behavior of the check to be stricter: now it's
using `as S?` instead of `as? S`, which means that if the remapped
symbol is present in `fakeOverridesMap`, then it must be of the same
type.
