We were generating two reabstraction thunks from
(Generator.Element, Generator.Element) -> Bool
back to
(Generator.Element, Generator.Element) -> Bool
for the let bitcast.

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.

The internal details of ErrorType are still being designed.
They should be underscored in the meantime to
indicate they are still evolving.
Implements rdar://problem/20927102.

This came out of today's language review meeting.
The intent is to match #available with the attribute
that describes availability.
This is a divergence from Objective-C.

This change attempts to introduce the functionality without being too
disruptive. After we branch, I want to consolidate some of the runtime
functions and implement this functionality for multi-payload enums
as well, which requires adding new runtime metadata.
Example:
(swift) enum Color { case Red, Green, Blue(Int) }
(swift) print(Color.Red)
REPL.Color.Red
(swift) print(Color.Blue(5))
REPL.Color.Blue(5)
Implements <rdar://problem/18334936>.

This change tries to recover the performance regression in map() that
was caused by moving map() to a protocol extension and degrading the
static type information (when mapping a collection, we only know that it
is a sequence). Adding map() to the witness table allows us to provide
a specialized implementation for collections, and hopefully recover the
lost performance.

This time with a dictionary instead of array literal, and with a test
Unless the bots break (and I will keep a more careful eye out for that this time), this will fix rdar://problem/20861708

Members of protocols found via unqualified name lookup are mapped to
their corresponding witnesses, as we do for qualified name
lookup. This is the bulk of the compiler changes for
rdar://problem/20509152. Performing this mapping for unqualified name
lookup of types will follow.

The targeted functions all take over a second to type-check with my debug
compiler (found using -debug-time-function-bodies). The top two---the two
replaceRange implementations---took about a minute each; this change
knocks them down to 30-40s.
All of this is just breaking expressions apart, and the expressions aren't
even that complicated. I'm concerned that we have a serious performance
regression around the use of lazy(), and I've filed rdar://problem/20875936
so we can look into it. The test change is particularly concerning; there's
a ridiculous difference between 'lazy(...).reverse()' and
'lazy(...).reverse().reverse()'.
No intended functionality change.
