When a substring gets bridged to NSString, it loses the initial offset,
therefore APIs that accept or return StringIndex ranges should handle
this case explicitly by adding/subtracting the substring start offset.
Fixes <rdar://problem/33873277>
I failed to merge the upstream changes to swift-corelibs-foundation at the same
time as I merged that #9806, and it broke on linux. Going to get it right this
time.
- remove additional 'characters' references from String docs
- improved language around escaping pointer arguments
- key path type abstracts
- codable type abstract revisions
- a few more NSString API fixes
* removing .characters from examples
* beginning new String doc revisions
* improvements to the String Foundation overlay docs
* minor revisions elsewhere
* [stdlib] String : RangeReplaceableCollection & BidirectionalCollection
* Add source compatibility hack for Swift.max
* Add source compatibility hack for Swift.min
* Remove redundant conformance in benchmarks
* Fix stupid typo I thought I'd already pushed
* XFAIL testing now-redundant conformance
* XFAIL an IDE test for now
Some cases of using isSuperset can cause crashes, this was caused by improper subclassing callouts; this pr resolves those failures (and provides unit tests for that case)
The cases where the bridge was traversed too much now only causes a single bridge out call (without needing to reallocate or thrash retain/release)
String.components(separatedBy: CharacterSet) should be considerably faster now not only for more apporpriate bridging calls but also no longer needing to bridge arrays back and forth.

Apple and the Swift community has settled on this style:

Swift 3 unintentionally allowed collection casts from, e.g.,
Set<AnyHashable> to Set<NSObject>, when in fact the object
representation of the AnyHashable might not be an NSObject. Fix up our
tests and overlays that ran afoul of this rule.
String.init(format:locale:arguments:) contained a check to make sure
that the format string didn't try to format more arguments than were
actually passed. However, the check didn't guarantee safety (since the
format specifiers didn't have to match the *type* of the passed
argument) and contained bugs such as
https://bugs.swift.org/browse/SR-1378. Since the check was not a
guarantor of safety and was wrong, it is hereby removed.
If checks are to be reintroduced, they should both be correct and
guarantee complete safety. Doing this check correctly is a nontrivial
job (the code in Clang to parse such specifiers is well over 500 lines),
and should be taken on as a distinct project.
Adds an explicit @escaping throughout the standard library, validation
test suite, and tests. This will be necessary as soon as noescape is
the default for closure parameters.
Update for SE-0107: UnsafeRawPointer
This adds a "mutating" initialize to UnsafePointer to make
Immutable -> Mutable conversions explicit.
These are quick fixes to stdlib, overlays, and test cases that are necessary
in order to remove arbitrary UnsafePointer conversions.
Many cases can be expressed better up by reworking the surrounding
code, but we first need a working starting point.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.
As proposed in SE-0107: UnsafeRawPointer.
`void*` imports as `UnsafeMutableRawPointer`.
`const void*` imports as `UnsafeRawPointer`.
Occurrences of `UnsafePointer<Void>` are replaced with UnsafeRawPointer.
* Migrate overlays from UnsafePointer<Void> to UnsafeRawPointer.
This requires explicit memory binding in several places,
particularly in NSData and CoreAudio.
* Fix a bunch of test cases for Void->Raw migration.
* qsort takes IUO values
* Bridge `Unsafe[Mutable]RawPointer as `void [const] *`.
* Parse #dsohandle as UnsafeMutableRawPointer
* Update a bunch of test cases for Void->Raw migration.
* Trivial fix for the SceneKit test case.
* Add an UnsafeRawPointer self initializer.
This is unfortunately necessary for assignment between types imported from C.
* Tiny simplification of the initializer.
* Migrate from `UnsafePointer<Void>` to `UnsafeRawPointer`.

This removes the `_core` property from UnicodeScalarView.Index
and moves any remaining index-moving logic from the index to
the view in UnicodeScalarView and CharacterView.
It should have the same form as the argument to NS_SWIFT_NAME
in Objective-C, except that it permits operators and (currently)
disallows instance members and properties. We do get to share the
same parsing code, at least.
This actually caught an error in the Foundation overlay!
Groundwork for SR-1008.
