* Refactor Indices and Slice to use conditional conformance
* Replace ReversedRandomAccessCollection with a conditional extension
* Refactor some types into struct+extensions
* Revise Slice documentation
* Fix test cases for adoption of conditional conformances.
* [RangeReplaceableCollection] Eliminate unnecessary slicing subscript operator.
* Add -enable-experimental-conditional-conformances to test.
* Gruesome workaround for crasher in MutableSlice tests
* [SR-4005] Allow heterogenous comparisons in elementsEqual
When a user is supplying a predicate to compare the type equivalence
isn’t required
* elementsEqualWithPredicate tests
Compares a string of a number with an integer value by using the
elementsEqualPredicate closure
* Update test expectations to use new sequence element types
* Update hardcoded test to reference sequence
Make the Indices types conform to the appropriate Collection protocol:
* Collection.Indices: Collection
* BidirectionalCollection.Indices: BidirectionalCollection
* RandomAccessCollection.Indices: RandomAccessCollection
Introduce (recursive) constraints that make the *Collection constraint
of SubSequence match that of its enclosing *Collection, e.g.,
MutableCollection.SubSequence conforms to MutableCollection.
Fixes rdar://problem/20715031 and more of SR-3453.
Addressed ABI FIXME’s #4, #5, #104 and #105, making Sequence’s
SubSequence conform to Sequence, with the same element type, and for
which the SubSequence of a SubSequence is the same SubSequence.
Fixes SR-318 / rdar://problem/31418206.

Part of ABI FIXME #99, this gives us some nice consistency that
ensures that slicing a SubSequence gives us another SubSequence. There
are two source-compatibility implications to this change:
* Collections now need to satisfy this property, which could not be
expressed in Swift 3. There might be some Collections that don't
satisfy this property, and will break with the Swift 4 compiler
*even in Swift 3 compatibility mode*. Case in point...
* The Lazy collection types were formulated as a lazy collection of
the base slice (e.g., LazyCollection<ArraySlice<T>>) rather than as
a slice of the lazy collection (e.g.,
Slice<LazyCollection<Array<T>>). The former doesn't meet the new
requirements, so change to the latter.
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.
* 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.

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.
These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
This commit adds a fix-it to remove @discardableResult on functions that return Void or Never. The fix-it is at the warning level. A test was added to verify that the fix-it removes the @discardableResult. This issue was reported in SR-3359:
https://bugs.swift.org/browse/SR-3359
Changes:
TypeCheckAttr.cpp: implemented AttributeChecker::visitDiscardableResultAttr to add a fix-it to remove @discardableResult on functions returning Void or Never.
DiagnosticsSema.def: Added a warning with a diagnostic message.
LoggingWrappers.swift.gyb, HashedCollections.swift.gyb: Removed @discardableResult on functions returning Void.
fixits-apply-all.swift, fixits-apply-all.swift.result: Added tests to verify that @discardableResult is removed from functions returning Void or Never.
