The ALL_APPLE_PLATFORMS idiom is wrong because any new platforms that
get added will not have dependencies by default and it's breaking the
standalone overlay script for platforms that use it. Moreover, some of the
overlays list all platforms even though they could have used
ALL_APPLE_PLATFORMS.
Some cases of using isSuperset can cause crashes, this was caused by improper subclassing callouts; this pr resolves those failures (and provides unit tests for that case)
The cases where the bridge was traversed too much now only causes a single bridge out call (without needing to reallocate or thrash retain/release)
String.components(separatedBy: CharacterSet) should be considerably faster now not only for more apporpriate bridging calls but also no longer needing to bridge arrays back and forth.
Resolves the following issues:

Previously it was part of swiftBasic.
The demangler library does not depend on llvm (except some header-only utilities like StringRef). Putting it into its own library makes sure that no llvm stuff will be linked into clients which use the demangler library.
This change also contains other refactoring, like moving demangler code into different files. This makes it easier to remove the old demangler from the runtime library when we switch to the new symbol mangling.
Also in this commit: remove some unused API functions from the demangler Context.

The ABI mismatch here would cause a crash in cases when the Foundation overlay wasn't available, or its implementation of swift_Foundation_getErrorDefaultUserInfo wasn't dynamically resolvable, such as in a stripped statically linked binary. Fixes rdar://problem/29173132.
This avoids indirection by making calls directly to the C implementations which prevents potentials of mismatched intent or changes of calling convention of @_silgen. The added benefit is that all of the shims in this case are no longer visible symbols (anyone using them was not authorized out side of the Foundation overlay). Also the callout methods in the headers now all share similar naming shcemes for easier refactoring and searching in the style of __NS<class><action> style. The previous compiled C/Objective-C source files were built with MRR the new headers MUST be ARC by Swift import rules.
The one caveat is that certain functions MUST avoid the bridge case (since they are part of the bridging code-paths and that would incur a recursive potential) which have the types erased up to NSObject * via the macro NS_NON_BRIDGED.
The remaining @_silgen declarations are either swift functions exposed externally to the rest of Swift’s runtime or are included in NSNumber.gyb which the Foundation team has other plans for removing those @_silgen functions at a later date and Data.swift has one external function left with @_silgen which is blocked by a bug in the compiler which seems to improperly import that particular method as an inline c function.
URLError.Code was an enum, which is a bad idea because it can lead to
crashes if the enum doesn't cover a legitimate error code. Convert it to
a struct to match how CocoaError.Code is implemented.
Also add the missing cases `. dataLengthExceedsMaximum` and
`. appTransportSecurityRequiresSecureConnection`, and fix the broken
cases `.backgroundSessionRequiresSharedContainer`,
`.backgroundSessionInUseByAnotherProcess`, and
`.backgroundSessionWasDisconnected`.
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.
Use the generic type lowering algorithm described in
"docs/CallingConvention.rst#physical-lowering" to map from IRGen's explosion
type to the type expected by the ABI.
Change IRGen to use the swift calling convention (swiftcc) for native swift
functions.
Use the 'swiftself' attribute on self parameters and for closures contexts.
Use the 'swifterror' parameter for swift error parameters.
Change functions in the runtime that are called as native swift functions to use
the swift calling convention.
