* Give Sequence a top-level Element, constrain Iterator to match
* Remove many instances of Iterator.
* Fixed various hard-coded tests
* XFAIL a few tests that need further investigation
* Change assoc type for arrayLiteralConvertible
* Mop up remaining "better expressed as a where clause" warnings
* Fix UnicodeDecoders prototype test
* Fix UIntBuffer
* Fix hard-coded Element identifier in CSDiag
* Fix up more tests
* Account for flatMap changes
* Add sliceability tests for Unsafe(Raw)BufferPointer.
Improve the generic sliceability tests to verify that SubSequence indices are
compatible with their parents indices.
* Fix and enable testing stdlib Collection instances.
Top-level entry points fully testing a collection instance:
check${Traversal}Collection
One level of recursion into all slices of the collection instance
O(n^2). (Not combinatorial).
Previously, checkCollection() did nothing. So much of the testing infrastructure was inactive. Now it runs all forward collection tests.
Fixes a bug in subscriptRangeTests.
The UnsafeRawBufferPointer and Data collection testing is disabled and
will be fixed in the following commit.
* Give UnsafeRawBufferPointer a distinct slice type.
SubSequence = RandomAccessSlice<Self>
* Fix raw buffer pointer tests after changing the API
* Add UnsafeRawBuffer(rebasing:) initializers.
Allows converting a raw slice into a zero-based raw buffer,
which is a common operation on flat memory.
Add and update UnsafeRawBufferPointer unit tests.
* Do not run recursive O(n^2) collection slice testing on large collections.
Now, even with collection unit testing wired up, the validation tests
take the same amount of time to execute.
* Add init(rebasing:) to UnsafeBufferPointer.
This is required for consistency with UnsafeRawBufferPointer.
* Update CHANGELOG.md for SE-0138 amendment: UnsafeRawBufferPointer slice type.
This revises and expands upon documentation for the standard library's
unsafe pointer types. This includes typed and raw pointers and buffers,
the MemoryLayout type, and some other top-level functions.

Unsafe[Mutable]RawBufferPointer is a non-owning view over a region of memory as
a Collection of bytes independent of the type of values held in that
memory. Each 8-bit byte in memory is viewed as a `UInt8` value.
Reads and writes on memory via `Unsafe[Mutable]RawBufferPointer` are untyped
operations. Accessing this Collection's bytes does not bind the
underlying memory to `UInt8`. The underlying memory must be bound
to some trivial type whenever it is accessed via a typed operation.
In addition to the `Collection` interface, the following methods from
`Unsafe[Mutable]RawPointer`'s interface to raw memory are
provided with debug mode bounds checks: `load(fromByteOffset:as:)`,
`storeBytes(of:toByteOffset:as:)`, and `copyBytes(from:count:)`.
This is only a view into memory and does not own the memory. Copying a value of
type `UnsafeMutableRawBufferPointer` does not copy the underlying
memory. Assigning an `Unsafe[Mutable]RawBufferPointer` into a value-based
collection, such as `[UInt8]` copies bytes out of memory. Assigning into a
subscript range of UnsafeMutableRawBufferPointer copies into memory.
