* Eradicate IndexDistance associated type, replacing with Int everywhere
* Consistently use Int for ExistentialCollection’s IndexDistance type.
* Fix test for IndexDistance removal
* Remove a handful of no-longer-needed explicit types
* Add compatibility shims for non-Int index distances
* Test compatibility shim
* Move IndexDistance typealias into the Collection protocol
* 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.

* Unify the capitalization across all user-visible error messages (fatal errors, assertion failures, precondition failures) produced by the runtime, standard library and the compiler.
* Update some more tests to the new expectations.
* Create Swift libSyntax API
This patch is an initial implementation of the Swift libSyntax API. It
aims to provide all features of the C++ API but exposed to Swift.
It currently resides in SwiftExperimental and will likely exist in a
molten state for a while.
* Only build SwiftSyntax on macOS
