Slava Pestov 00c1279dbb Reflection: Compute if types are bitwise takable 
Bitwise takability is now part of the layout of a type, because
non-bitwise takable types are never stored inline in an
existential or resilient global's buffer, even if they would
fit.

The basic rule is that weak references, unknown-refcounted
unowned references, and aggregates that contain them, are not
bitwise takable, whereas everything else is bitwise takable.

Also, since the bitwise takable for an unowned reference
depends on the reference counting style, we have to record the
superclass of a protocol, if any, to correctly determine the
reference counting style of the protocol existential.
