Add the necessary build-configuration disjunct to enable run-time
availability checks on watchOS.
The std lib tests for this on the watch simulator currently fail for unrelated
reasons <rdar://problem/20932146>. I have tested this manually with the
simulator.

Change _stdlib_isOSVersionAtLeast on tvOS to actually check the running
OS version rather than always returning false. It still always returns false on
watchOS; rdar://problem/20234735 tracks that.

The rule changes are as follows:
* All functions (introduced with the 'func' keyword) have argument
labels for arguments beyond the first, by default. Methods are no
longer special in this regard.
* The presence of a default argument no longer implies an argument
label.
The actual changes to the parser and printer are fairly simple; the
rest of the noise is updating the standard library, overlays, tests,
etc.
With the standard library, this change is intended to be API neutral:
I've added/removed #'s and _'s as appropriate to keep the user
interface the same. If we want to separately consider using argument
labels for more free functions now that the defaults in the language
have shifted, we can tackle that separately.
Fixes rdar://problem/17218256.

The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.
See stdlib/{public,internal,private}/README.txt for more information.
