* Make Range conditionally a Collection
* Convert ClosedRange to conditionally a collection
* De-gyb Range/ClosedRange, refactoring some methods.
* Remove use of Countable{Closed}Range from stdlib
* Remove Countable use from Foundation
* Fix test errors and warnings resulting from Range/CountableRange collapse
* fix prespecialize test for new mangling
* Update CoreAudio use of CountableRange
* Update SwiftSyntax use of CountableRange
* Restore ClosedRange.Index: Hashable conformance
* Move fixed typechecker slowness test for array-of-ranges from slow to fast, yay
* Apply Doug's patch to loosen test to just check for error
This new format more efficiently represents existing information, while
more accurately encoding important information about nested generic
contexts with same-type and layout constraints that need to be evaluated
at runtime. It's also designed with an eye to forward- and
backward-compatible expansion for ABI stability with future Swift
versions.
clang is miscompiling some swiftcall functions on armv7s.
Stop using swiftcall in some places until it is fixed.

NSString has a stricter concept of equality than Swift’s String, so it is possible to construct NSDictionary/NSSet instances that contain duplicate keys according to Swift’s definition of string equality. This change improves how we handle these cases by coalescing the duplicate keys (keeping a single value).

* Remove a bunch of Default(Bidirectional|RandomAccess)Indices usage from stdlib and test
* Remove some DefaultRandomAccessIndices and IndexDistance usage from Foundation
* Remove no-longer-used internal type in Existentials.swift
* Get rid of indicesForTraversal
Inserting and removing a single Unicode.Scalar in a CharacterSet must not
attempt to create a Range<Unicode.Scalar> because the upperBound value might
not always be a valid UnicodeScalar.
This fixes a regression to the fix for SR-2988.
* [Foundation] Byte access and methods that funnel to byte access for slices of discontiguous data (ala backed by dispatch_data_t) should void heap corruption and walking off the ends of buffers
* add missing parens on test_byte_access_of_discontiguousData
* Use the proper byte count in testing
XCTest had XCAssert(Not)Equal overloads for optionals, arrays
(including contiguous arrays and array slices), and dictionaries to
work around the lack of conditional conformances to Equatable. Now
that we have the latter, remove the former.
Fixes rdar://problem/17924430.
* [runtime] Clean up symbols in error machinery.
* [runtime] Clean up symbols in Foundation overlay.
* [runtime] Clean up symbols in collections and hashing.
* [runtime] Remove symbol controls from the Linux definition of swift_allocError.
* [tests] Add more stub functions for tests that link directly to the runtime.
...as detected by initializing an individual field without having
initialized the whole object (via `self = value`).
This only applies in pre-Swift-5 mode because the next commit will
treat all cross-module struct initializers as delegating in Swift 5.
