At some point I want to propose a revised model for exports, but for now
just mark that support for '@exported' is still experimental and subject
to change. (Thanks, Max.)
CNErrorDomain is lacking proper availability annotations, and
explicitly linking with -weak_framework is not working reliably. For
now, just remove the overlay to solve rdar://problem/21030937. We'll
bring it back when rdar://problem/21032649 makes it into all of the
builds we care about.

Fixes rdar://problem/21030937, which came about because CNErrorDomain
is missing availability information, so we generate a normal external
reference rather than a weak one.
Swift SVN r28824
Introduce a number of small overlays to bridge the NSError domains for
a number of frameworks into existing imported enums. This batch only
covers cases where there is an existing NS_ENUM describing the codes
for the domain, so we need only extend that enum to provide the
appropriate _BridgedNSError conformance.
This is the bulk of rdar://problem/20536610.
