Chris Tate 4a5ddadd3d Memoize an empty literal's type separately as a union arm ...

The type mapper maps the type inferred from an empty object literal to the
empty record as an arm of an unreduced union and to a checked-dynamic
value elsewhere, but both answers shared one memo entry. Once the type had
been mapped on its own, a union such as `typeof empty | DataView` reused
the dynamic answer for its arm and refused (SC2009). The memo key now
includes whether the mapping is for such an arm.
