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.)
Remove a temporary hack added in r29026 that disabled availability checking
for the WatchKit overlay due to SDK update issues. It is no longer needed.

Addresses a bitcode linking problem when linking with the SDK overlays,
which are built against the internal SDK, against a program built
against the public SDK, which does not have

The <Redacted>13A261 iOS SDK adds an availability attribute marking the imported
WatchKitErrorCode enum as available only on iOS 8.2 and newer. The WatchKit overlay
has a protocol extension for WatchKitErrorCode, so mark the extension as only available
on 8.2 and newer. On <Redacted>13A261 this silences a diagnostic complaining that
WatchKitErrorCode is only available on 8.2 and newer.
However, on <Redacted>13A254 this new annotation itself causes an error because on that
SDK WatchKitErrorCode claims to be available on all iOS versions and yet the conformance
would only hold on 8.2 and newer. To make this second diagnostic go away, this
commit temporarily disables availability checking for the WatchKit overlay.
rdar://problem/21099550 tracks re-enabling availability checking when we update the bots,
etc. to <Redacted>13A261.

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.
