be37cd904b [stdlib] Trap invalid Ranges of Comparable Indexes 
When the Index type of a Range is Comparable, we can reject invalid
ranges at their formation.

It might be worth injecting some checkability concept into ForwardIndex
so that even in generic contexts where Comparability is unknown, we can
do this same check in the Range constructor.

Also, remove pattern matching support for Ranges of RandomAccessIndex,
as that is covered by Interval.

Fixes <rdar://problem/16254937> (#Seed 4: Ranges with negative strides
are broken) to the extent possible (it's still possible to form an
invalid Range of indices that are not Comparable)

Fixes <rdar://problem/17164391> (Swift: Using ranges in for in for
counting down, causes the loop to go inifinely)

Fixes <rdar://problem/17580871> (Swift: Closed range with negative
endpoint excludes that endpoint)

cb050eee52 [stdlib] Add Interval support 
This allows 0.0..<10.3 and 0.1...4.4 to work properly in pattern
matching.

Fixes <rdar://problem/12016900> (#Seed 4: add a "contains" method to the
range types) by making "contains" available on Interval

Addresses <rdar://problem/16254937> (#Seed 4: Ranges with negative
strides are broken) by making the formation of an invalid Interval a
runtime error.

Fixes <rdar://problem/16304317> (Range<T> has limited awesomeness: it is
restricted to types that conform to ForwardIndex)

Fixes <rdar://problem/16736924> (#Seed 4: Enable range inclusion pattern
matching for all types that conform to Equatable and Comparable)

Addresses <rdar://problem/16846325> (#Seed 4: Introduce index range) by
distinguishing Range (which operates on indices) from Interval

Fixes <rdar://problem/17051263> (Pattern-matching a Double range with an
infinite endpoint triggers an assertion failure)

Fixes <rdar://problem/17051271> (#Seed 4: Pattern-matching Double ranges
excludes fractional values)

a5c079af59 Replace the class_protocol attribute with a "class" requirement. 
This only tackles the protocol case (<rdar://problem/17510790>); it
does not yet generalize to an arbitrary "class" requirement on either
existentials or generics.

6d1095f44e Protocol names end in "Type," "ible," or "able" 
Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able."  Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.

There are obvious improvements to make in some of these names, which can
be handled with separate commits.

Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.

ee06efdd2c stdlib/Dictionary: when bridging Dictionary of non-verbatim-bridged 
types to NSDictionary, perform bridging operation in O(1), and defer
bridging of the contents until the NSDictionary is accessed

There is no cache for bridged keys and values; the Swift NSDictionary
will return values with different pointer values when a given key is
repeatedly accessed.

Part of rdar://17556319

Does not fix the O(N) performance of objc thunks, because Dictionary is
not recognizing its own native storage when bridging from Objective-C.

8882999b63 Add Array semantic model. 
This unblocks work on bounds and mutable check hoisting. Pete is also
tuning -O3 Array performance, which should be done on top of this
patch.

Overall, this significantly improves performance, but there is one
issue that causes regressions on Hash and QuickSort at -O3 only. This
patch does not cause the performance issue. It is already a serious
problem that needs to be fixed. This patch just adds a level of benign
function calls that further exposes the existing performance problem.
We are independently working on fixing this: <rdar://problem/17634697>
Array access forces retain/release of storage object for each inlined
call.
