Doug Gregor 9c03b4f924 Miscellaneous cleanups for array bridging in the type checker. ...

Use protocol conformance checks whenever we want to determine whether
a value type is bridged to an Objective-C class, which is simpler and
more robust. Clean up some of the type checker code around bridging,
using TypeBase::isEqual() to compare types and looking through type
sugar more regularly.

As part of this, move Array's conformance to
_ConditionallyBridgedToObjectiveC into the Foundation overlay. This
lets us use NSArray as the bridged type (which is clearer than using
CocoaArray), and follows what we're doing for dictionary bridging.


As part of this, move Array's bridged-to-
