Add_library doesn't build per-target variants of the library, but
add_swift_library does. Also changed to install as part of stdlib, since it's
needed even if you aren't building the compiler.
replace ProtocolConformanceTypeKind with TypeMetadataRecordKind
metadata reference does not need to be indirectable
more efficient check for protocol conformances
remove swift_getMangledTypeName(), not needed yet
kill off Remangle.cpp for non-ObjC builds

When I originally added this I did not understand how dtrace worked well enough.
Turns out we do not need any of this runtime instrumentation and we can just
dynamically instrument the calls.
This commit rips out the all of the static calls and replaces the old
runtime_statistics dtrace file with a new one that does the dynamic
instrumentation for you. To do this one does the following:
sudo dtrace -s ./swift/utils/runtime_statistics.d -c "$CMD"
The statistics are currently focused around dynamic retain/release counts.
Move the ObjC internal declarations to a public runtime header so they can be shared, and rename _swift_deallocClassInstance to the more descriptive name swift_rootObjCDealloc (and make it only available with ObjC interop).
Set up a separate libSwiftStubs.a archive for C++ stub functionality that's needed by the standard library but not part of the core runtime interface. Seed it with the Stubs.cpp and LibcShims.cpp files, which consist only of stubs, though a few stubs are still strewn across the runtime code base.
Revert "Add test cases to exercise the native String vs cocoa buffer String path."
Revert "stdlib: Add back a test I removed"
Revert "stdlib: Fix hasPrefix,hasSuffix tests"
Revert "stdlib: Add documentation for the cached ascii collation tables"
This reverts commit 31493, 31492, 31491, 31490, 31489.
There are linking errors in SwiftExternalProjects (we probably have to link
against libicucore somewhere).

Reapply of 31474 with a fix in _compareCocoaBuffer to use the bufferSizeRhs
variable instead of bufferSizeLhs for the right hand side buffer.
We no longer create intermediate NSString copies to compare and hash swift
Strings. Instead we call directly into the ICU library.
I measured a 1.2 to 2x improvement on dictionary benchmarks as a result of this.
The SuperChars benchmark is also about 1.2x faster because of this.
Pure ASCII comparison has gotten a little bit slower (20% on a pure comparison
micro-benchmark) because we no longer do a memcmp. Doing a memcmp on ASCII is
not the same as the default unicode collation. Instead we have to a string scan.
The default unicode collation does not order like ASCII does and ignores
characters (for example the \0 character).

Revert "stdlib: Add back a test I removed"
Revert "Add test cases to exercise the native String vs cocoa buffer String path."
Revert "stdlib: Move the darwin String implementation over to use the ICU library."
This reverts commit r31477, r31476, r31475, r31474.
Commit r31474 broke the ASAN build.

Un-revert the below commits with the following addition:
add declarations for posix_spawn related APIs to SwiftPrivateDarwinExtras.
posix_spawn-related APIs aren't available in the public SDKs, so force past
the availability by creating our own stubs in the internal DarwinExtras
library.

CMake: build all platforms except watchOS using the public SDK
Covers rdar://problem/21145996.
A step towards rdar://problem/21099318.
Switch SDK overlays to use the public SDK
I had to cut the dependency on CrashReporterClient.h and reimplement
some of that code inline in the Swift runtime. This shoud be OK (even
though not very clean), since the layout of CrashReporter sections is
ABI.

Our hack to generate a unique name by appending the class pointer doesn't produce a stable class name that can persist in NSKeyedArchiver, or eventually be used as a key for dynamic runtime instantiation. Generate a proper mangled name for the class instance by building a demangling AST from the metadata nodes and feeding it into the remangler. Should fix rdar://problem/18884563, though I need to try using an archiver with a generic class to verify.
Swift SVN r29316
Configure the runtime to build with -Wglobal-constructors, and Lazy-fy almost everything that gets flagged. (I gave "swift_isaMask" a pass since that's almost definitely hot enough to warrant a static initialization.) Make some improvements to the Lazy wrapper, using aligned_storage to ensure that it's trivially constructed and destructed.

These should all apply to any Darwin platform, and the current behaviour
was breaking cross-compilation.
Introduces a SWIFT_DARWIN_VARIANTS pattern, to be used as follows:
if(SWIFT_HOST_VARIANT MATCHES "${SWIFT_DARWIN_VARIANTS}")
Also fix one place where I checked the CMAKE_SYSTEM_NAME instead of the
host variant that I recently introduced. I haven't attempted to find
the rest of the places we're doing this though.

Runtime should use LINK_LIBRARIES to link to ICU, since it is a static
archive, and we need this link dependency to be propagated to the
libswiftSwiftCore library. I have no idea why it linked correctly
worked before.
Swift SVN r25881
The standard library has grown significantly, and we need a new
directory structure that clearly reflects the role of the APIs, and
allows future growth.
See stdlib/{public,internal,private}/README.txt for more information.
