If the struct is resilient, it is passed indirectly. Even if we decide to
make it fixed layout, it's best to remove as many implicit ABI assumptions
as possible from @_silgen_name function calls.
Fixes <rdar://problem/28673618>.
From the Swift documentation:
"If you define an optional variable without providing a default value,
the variable is automatically set to nil for you."
RangeReplaceableCollection.SubSequence should be a
RangeReplaceableCollection. Data implements RangeReplaceableCollection,
but sets SubSequence to MutableRandomAccessSlice that is not a
RangeReplaceableCollection.
This commit changes Foundation.Data.SubSequence to
MutableRangeReplaceableRandomAccessSlice.
Fixes rdar://problem/28330713.
This provides a hint to the proper API to use for struct Data when developers are migrating from NSData.
Purely a fixit addition (no actual functional code)
<rdar://problem/26206061> Missing fixit for Data.getBytes
As of now:
* old APIs are just marked as `deprecated` not `unavaiable`. To make it
easier to co-operate with other toolchain repos.
* Value variant of API is implemented as public @private
`_ofInstance(_:)`.
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.
This iterator uses an inline 32-byte buffer so it doesn't have to call
copyBytes(to:count:) for every single byte. It results in an approximate
6x speedup on my computer.

* 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`.

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.
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.
