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.
Reverts c5bf2ec (#13299).

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
* [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.
When a substring gets bridged to NSString, it loses the initial offset,
therefore APIs that accept or return StringIndex ranges should handle
this case explicitly by adding/subtracting the substring start offset.
Fixes <rdar://problem/33873277>
* Mutations of slices of data should preserve relative indexing as well as cow semantics of slices
* Ensure hashes of ranges are uniform to the expected hash for Data
* Correct a few mistakes in the slice mutation tests
* Update sequence initializations to avoid directly calling mutableCopy which prevents slice offset mismatches
* Avoid invalid index slices in creating mirrors
* Restore the original Data description
* Resetting a slice region should expand the slice to the maximum of the region (not a out of bounds index of the backing buffer)
* Remove stray comment and use a stack buffer for sequence appending
* Return false when allocations fail in _resizeConditionalAllocationBuffer (not yet in use)
* Enumeration of regions of a slice should be limited to the slice range in the case of custom backing (e.g. dispatch_data_t)
* adjust assertion warnings for data indexes that are negative
JSONEncoder and PropertyListEncoder both use NSNumber to box Bool values. An encoded Bool can be coerced to any numerical type during decoding because (false as NSNumber).intValue == 0. As a remedy, all of the unbox(_:as:) methods of _JSONDecoder and _PlistDecoder for numerical types include a check that the value is not identical to either kCFBooleanTrue or kCFBooleanFalse, and throw a DecodingError._typeMismatch(at:expectation:) if this check fails.
* 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.
