Slava Pestov 1dd527ef4e Sema: Fix crash when synthesizing RawRepresentable conformance with non-Equatable raw type ...

The error recovery logic around derived conformances is a little bit
tricky. Make sure we don't crash if a type explicitly provides a
RawValue type witness that is not equatable, but omits the witnesses
for init(rawValue:) and the rawValue property.

Fixes <rdar://problem/58127114>.
