7e11f1822c Implement fixed-width integer conversions from binary floating point 
Make internal stdlib function public because it is called from stdlib tests

Add some first-thought optimizations

762731940d Force specialization of a very big function quotientAndRemainder for the most popular values of generic type parameters. 
This reduces the amount of work to be done on the client side, because specializations from the stdlib can be used there.

7c705c3a75 [stdlib] Deprecate String/Substring.CharacterView 
CharacterView is now entirely redundant in Swift 4. Deprecate its
use. This also allows us to schedule the unbreaking of
String.CharacterView leakiness without a hard source break.

64e0e1859e [stdlib] Deprecate popFirst in Swift 3.2 
Add a deprecation warning for use of popFirst even with -swift-version
3, as it's prone to leaks under the old model. Test cases added.

3243b8a59f [stdlib] Availability checking for String.*View.popFirst 
Collection's popFirst is only present when the Collection is its own
SubSequence type. String and String's views are no longer their own
SubSequenes, so popFirst is no longer present. Unfortunately, this
breaks code in swift-version 3 and it also gives a terrible diagnostic
to users. This change introduces an implementation for swift-version 3
mode and better diagnostics for Swift 4 code. Tests included.

fbdcbee7a2 Remove previous hack for SR-5206 
As a temporary workaround for SR-5206, certain Foundation types which had custom behavior in JSONEncoder and JSONDecoder were granted special knowledge of those types internally in order to preserve strategies on encode/decode.

This replaces that special knowledge with a more general-purpose fix that works for all types and all encoders/decoders.

41c53ae729 [stdlib] Give Substring its own views 
This necessary for ensuring the property that String doesn't keep
inaccessible memory alive.  For example, before this change,

    String(s.dropFirst().unicodeScalars)

would compile and produce a String that owned inaccessible memory.
Now it no longer compiles.

String's view's SubSequences are the same as the Substring's
view. E.g. String.UnicodeScalarView.SubSequence is
Substring.UnicodeScalarView.

New compatibility inits added, to work around the fact that many
previously failable initializers are now non-failable.

10e9e336fe [stdlib] Fix bug in Substring's _persistentContent 
Substring's _persistentContent has a fast path that avoids a copy when
the Substring represents the entire outer String. It correctly
detected situations where the wrapped _StringCore was not itself a
slice, but was omitting the extra checks to make sure the Substring's
own range covered the entire String.

Test added.
