We can express the same using the `isUniquelyReferencedNonObjC` API.
- Rename `isUniquelyReferencedNonObjC` to `isKnownUniquelyReferenced`.
- Cleanup `ManagedBufferPointer` by removing holdsUniqueOrPinnedReference` and
renaming `holdsUniqueReference` to `isUniqueReference`.
- No longer promise to return false from `isKnownUniquelyReferenced` for @objc
class instances.

* 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.
and provide a fix-it to move it to the new location as referenced
in SE-0081.
Fix up a few stray places in the standard library that is still using
the old syntax.
Update any ./test files that aren't expecting the new warning/fix-it
in -verify mode.
While investigating what I thought was a new crash due to this new
diagnostic, I discovered two sources of quite a few compiler crashers
related to unterminated generic parameter lists, where the right
angle bracket source location was getting unconditionally set to
the current token, even though it wasn't actually a '>'.
All generic bridgeable types can bridge for all their instantiations now. Removing this ferrets out some now-unnecessary traps that check for unbridgeable parameter types.
We were using a precondition which crashes the program when invalid input is
provided. We want to provide a way to gracefully check and handle invalid input
or shutdown the program if necessary.

This commit defines the ‘Any’ keyword, implements parsing for composing
types with an infix ‘&’, and provides a fixit to convert ‘protocol<>’
- Updated tests & stdlib for new composition syntax
- Provide errors when compositions used in inheritance.
Any is treated as a contextual keyword. The name ‘Any’
is used emit the empty composition type. We have to
stop user declaring top level types spelled ‘Any’ too.
Foundation provides a number of specific operators defined in the
global scope. Push all of these into their corresponding types. This
cleanup helps verify that the SE-0091 implementation is generally
functional.
We currently specify a few internal ObjC classes. This commit ensures that they can not be accidentally exposed (and thus need to be supported) into the future. Luckily, NSData and NSDictionary/NSMutableDictionary already specify classForCoder in a general way. NSCharacterSet does not.
This commit also establishes unit tests to ensure all three types do not regress from this into the future.
Also, for completeness, it ensures classForArchiver and classForKeyedArchiver return appropriately as well.
Use the portable spelling for the nullability keywords (_Nullable, _Nonnullable,
_Null_unspecified) rather than the old spelling (__nullable, __nonnullable,
__null_unspecified). NFC.
Safely unwrap two optionals used in the compare that follows.
NFC, but this (or another work-around) will be required if either
SE-0121 or SE-0123 is approved.
