Use the KeyPath implementation's new support for instantiating and dealing with captures to lower the generic context required to dispatch computed accessors with dependent generics.
* IRGen: EmptyBoxType's representation cannot be nil because of a conflict with extra inhabitant assumption in indirect enums
We map nil to the .None case of Optional. Instead use a singleton object.

Programs using a statically linked build of the standard library need
to explicitly link against icucore. There are various potential
hacks^Wsolutions to this problem, and this is an attempt at a lesser
of evils approach.
Emit a linker directive to perform autolinking against icucore on
Darwin systems. This allows us to avoid hacking the compiler driver
and propagating that hack onto any build systems that don't go through
the driver.
Avoid a dependency on ICU headers on Apple platforms, rather than rely
on corelibs-foundation being checked out. This simplifies the
dependencies and unblocks build bots.
Adds in Linux platform support for our pthread TLS. Replace usage of
PTHREAD_KEYS_MAX with a sentinel value, as it's tricky to define
cross-platform and was only lightly used inside sanity checks.
Introduce shims for using UBreakIterators from ICU. Also introduce
shims for using thread local storage via pthreads.
We will be relying on ICU and UBreakIterators for grapheme
breaking. But, UBreakIterators are very expensive to create,
especially for the way we do grapheme breaking, which is relatively
stateless. Thus, we will stash one or more into thread local storage
and reset it as needed.
Note: Currently, pthread_key_t is hard coded for a single platform
(Darwin), but I have a static_assert alongside directions on how to
adapt it to any future platforms who differ in key type.

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:
rdar://problem/17281998
rdar://problem/26611771
rdar://problem/29738989
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.
* Go back to using static inline implementations of sqrt and remainder now that SR-2089 is resolved.
* Fix typo: sqrt -> squareRoot.
* Added test for constant-folding sqrt with -O.
* Added test case requested by jrose.
Changes:
* Terminate all namespaces with the correct closing comment.
* Make sure argument names in comments match the corresponding parameter name.
* Remove redundant get() calls on smart pointers.
* Prefer using "override" or "final" instead of "virtual". Remove "virtual" where appropriate.
The runtime and stubs are built for ALL targets, not specific ones. This allows
us to configure when cross-compiling to Windows again. Collapse the dual
addition of the swiftRuntime into a single build. This unifies the runtime
build for the apple and non-Apple SDKs. The difference here was the ObjC
interop sources. In order to deal with that unification add a CPP macro to
indicate whether the interop sources should be included or not.
We still have a bunch of redeclarations of Dispatch functions to avoid
the automatic bridging of dispatch_data_t and dispatch_block_t, but
mostly this is a vast reduction in complexity (and increase in safety).
