Slava Pestov d49f8fb6d9 AST: Introduce primitive AnyObject type ...

Add a 'hasExplicitAnyObject()' bit to ProtocolCompositionType
to represent canonical composition types containing '& AnyObject'.

Serialize this bit and take it into account when building
ExistentialLayouts.

Rename ProtocolCompositionType::getProtocols() to getMembers()
since it can contain classes now, and update a few usages that
need further attention with FIXMEs or asserts.

For now, nothing actually constructs these types, and they will
trigger arounds asserts. Upcoming patches will introduce support
for this.
