Apps don't weak-link our overlays today, so if the overlays strong-link
to frameworks apps won't launch on older OSs. This was causing failures
on the buildbot, but is actually a serious issue for our developers.

This allows us to remove the workaround generic overloads for "print" without sacrificing good diagnostics for its unavailable overloads. (rdar://problem/21499048, rdar://problem/21582758, rdar://problem/22126141)

Like decodeTopLevelObjectOfClass(_:forKey:), this API works very nicely
as a generic method in Swift, and this one is actually the one we expect
to be commonly used. One thing to note here is that these methods are
stricter than their ObjC counterparts: they will do a forced checked cast
even when the unarchiver does not use "secure" coding.
This depends on the previous commit; without it, we do not actually
enforce type safety for these methods.
The API notes change is to make the non-generic version of this method
unavailable so that it does not participate in overload resolution.
Without this we prefer the non-generic method unless there's a contextual
type for the result. I've filed rdar://problem/22243198 to track taking
this out once Foundation has updated their headers.

containsString and localizedCaseInsensitiveContainsString were
introduced in 10.10, release-noted, but never
documented (<rdar://22236574>), so we missed them.

dealloc_ref [destructor] is the existing behavior. It expects the
reference count to have reached zero and the isDeallocating bit to
be set.
The new [constructor] variant first drops the initial strong
reference.
This allows DI to properly free uninitialized instances in
constructors. Previously this would fail with an assertion if the
runtime was built with debugging enabled.

the regressions that r31105 introduced in the validation tests, as well as fixing a number
of other validation tests as well.
Introduce a new UnresolvedType to the type system, and have CSDiags start to use it
as a way to get more type information out of incorrect subexpressions. UnresolvedType
generally just propagates around the type system like a type variable:
- it magically conforms to all protocols
- it CSGens as an unconstrained type variable.
- it ASTPrints as _, just like a type variable.
The major difference is that UnresolvedType can be used outside the context of a
ConstraintSystem, which is useful for CSGen since it sets up several of them to
diagnose subexpressions w.r.t. their types.
For now, our use of this is extremely limited: when a closureexpr has no contextual
type available and its parameters are invalid, we wipe them out with UnresolvedType
(instead of the previous nulltype dance) to get ambiguities later on.
We also introduce a new FreeTypeVariableBinding::UnresolvedType approach for
constraint solving (and use this only in one place in CSDiags so far, to resolve
the callee of a CallExpr) which solves a system and rewrites any leftover type
variables as UnresolvedTypes. This allows us to get more precise information out,
for example, diagnosing:
func r22162441(lines: [String]) {
lines.map { line in line.fooBar() }
}
with: value of type 'String' has no member 'fooBar'
instead of: type of expression is ambiguous without more context
This improves a number of other diagnostics as well, but is just the infrastructural
stepping stone for greater things.

At -O I see about 10% improvement on Havlak, and 40% improvement on the recently
added array append benchmarks.
COWTree regresses by 15% because we hoist an append that is conditionally
executed. If we were to disallow hoisting of conditionally executed benchmarks
we would see big loses accross our benchmarks (for example, we would not hoist
out of nested loops anymore). So we will have to live with this regression.

The print abi changed so that there is no longer a way to print one item to a
stream without going through a vararg array. We call the print function in a
String initializer (e.g for string interpolation) incurring unnecessary
overhead. Use an internal specialized version of print instead.

There's still work left to do. In terms of next steps, there's still rdar://problem/22126141, which covers removing the 'workaround' overloads for print (that prevent bogus overload resolution failures), as well as providing a decent diagnostic when users invoke print with 'appendNewline'.

- advancedBy(n, limit:)
- distanceTo(end)
- Modernize the Index tests
- Use StdlibUnittest

(or in 'randomShuffle')
This violates our inout aliasing rules, and can cause a crash in certain
situations.
To try to prevent this in the future I've added a debugPrecondition check
to 'swap' that checks addresses. This will only catch inout violations
where neither argument uses writeback, and might some day be optimized
away. Right now, though, it does seem to catch some simple violations
(though not the one in the Radar), so hopefully it will at least help keep
us from introducing new problems.

...replacing it with the new, after passing API review!
* The lazy free function has become a property.
* Before we could extend protocols, we lacked a means for value types to
share implementations, and each new lazy algorithm had to be added to
each of up to four types: LazySequence, LazyForwardCollection,
LazyBidirectionalCollection, and LazyRandomAccessCollection. These
generic adapters hid the usual algorithms by defining their own
versions that returned new lazy generic adapters. Now users can extend
just one of two protocols to do the same thing: LazySequenceType or
LazyCollectionType.
* To avoid making the code duplication worse than it already was, the
generic adapters mentioned above were used to add the lazy generic
algorithms around simpler adapters such as MapSequence that just
provided the basic requirements of SequenceType by applying a
transformation to some base sequence, resulting in deeply nested
generic types as shown here. Now, MapSequence is an instance of
LazySequenceType (and is renamed LazyMapSequence), and thus transmits
laziness to its algorithms automatically.
* Documentation comments have been rewritten.
* The .array property was retired
* various renamings
* A bunch of Gyb files were retired.
