Record fields pushing each other out of scope in GHCi is unintuitive

If we try the following in GHCi:

:seti -XDuplicateRecordFields
data A = MkA { foo :: Int, bar :: Int }
data B = MkB { foo :: Int }
f r = r { foo = 3, bar = 4 }

we get an error:

<interactive>:4:7: error:
    * No constructor has all these fields: `foo', `bar'
    * In the expression: r {foo = 3, bar = 4}
      In an equation for `f': f r = r {foo = 3, bar = 4}

This is because the definition data B = MkB { foo :: Int } has shadowed the record field foo of A, making it only available under the qualifier Ghci1. The following record update is accepted:

g r = r { Ghci1.foo = 3, bar = 4 }

I will fix in !8686 (merged).
