Slava Pestov c4e804a7d1 AST: Fix TypeBase::hasSimpleTypeRepr() for ProtocolCompositionType ...

Prior to the introduction of noncopyable generics, a ProtocolCompositionType
was 'simple' if it was exactly 'Any' or 'AnyObject'. Now, there is a new
simple case, where we have a single inverse requirement '~Copyable' or
'~Escapable', and the old logic was never updated to account for this
possibility. Instead, it would ignore inverses, so it would claim that
a composition like `P & ~Copyable` was simple when it shouldn't be.

Fixes rdar://139465298.
