Keep calm: remember that the standard library has many more public exports
than the average target, and that this contains ALL of them at once.
I also deliberately tried to tag nearly every top-level decl, even if that
was just to explicitly mark things @internal, to make sure I didn't miss
something.
This does export more than we might want to, mostly for protocol conformance
reasons, along with our simple-but-limiting typealias rule. I tried to also
mark things private where possible, but it's really going to be up to the
standard library owners to get this right. This is also only validated
against top-level access control; I haven't fully tested against member-level
access control yet, and none of our semantic restrictions are in place.
Along the way I also noticed bits of stdlib cruft; to keep this patch
understandable, I didn't change any of them.

rangeOfCharacterFromSet(_:options:range:)
The underlying Objective-C API could return an NSRange of NSNotFound. Swift's
String.Index can not represent that, so change the API to return an optional
Swift Range<Index> instead.

stringWithBytes(_:length:encoding:) was passing an array to Objective-C
incorrectly, and a garbage NSString was being constructed as a result.
Unhide the initializer was accidentally hidden.

There's a bit of a reshuffle of the ExplicitCastExpr subclasses:
- The existing ConditionalCheckedCastExpr expression node now represents
"as?".
- A new ForcedCheckedCastExpr node represents "as" when it is a
downcast.
- CoerceExpr represents "as" when it is a coercion.
- A new UnresolvedCheckedCastExpr node describes "as" before it has
been type-checked down to ForcedCheckedCastExpr or CoerceExpr. This
wasn't a strictly necessary change, but it helps us detangle what's
going on.
There are a few new diagnostics to help users avoid getting bitten by
as/as? mistakes:
- Custom errors when a forced downcast (as) is used as the operand
of postfix '!' or '?', with Fix-Its to remove the '!' or make the
downcast conditional (with as?), respectively.
- A warning when a forced downcast is injected into an optional,
with a suggestion to use a conditional downcast.
- A new error when the postfix '!' is used for a contextual
downcast, with a Fix-It to replace it with "as T" with the
contextual type T.
Lots of test updates, none of which felt like regressions. The new
tests are in test/expr/cast/optionals.swift.
Addresses <rdar://problem/17000058>
Swift SVN r18556
Many changes in how we're presenting the NSString APIs on String, most
notably that we now traffic in String.Index and Range<String.Index>
rather than Int and NSRange. Also we present NSString initializers that
can fail only as factory functions, and factory functions that can't
fail only as init functions.
About 25% of the API changes here have been reviewd by the Foundation
guys, and testing is, as it has always been, admittedly spotty. Dmitri
is going to be writing some more comprehensive tests.

assert() and fatalError()
These functions are meant to be used in user code. They are enabled in debug
mode and disabled in release or fast mode.
_precondition() and _preconditionFailure()
These functions are meant to be used in library code to check preconditions at
the api boundry. They are enabled in debug mode (with a verbose message) and
release mode (trap). In fast mode they are disabled.
_debugPrecondition() and _debugPreconditionFailure()
These functions are meant to be used in library code to check preconditions that
are not neccesarily comprehensive for safety (UnsafePointer can be null or an
invalid pointer but we can't check both). They are enabled only in debug mode.
_sanityCheck() and _fatalError()
These are meant to be used for internal consistency checks. They are only
enabled when the library is build with -DSWIFT_STDLIB_INTERNAL_CHECKS=ON.
I modified the code in the standard library to the best of my judgement.

... unless we actually hit one of the confusing cases involving
multi-dimensional arrays (e.g., Int[]?[]), at which point one needs to
write parentheses <rdar://problem/16737035>.

This fixes a case where the Swift-variadic and C-varargs versions of
various initializers were superseding each other
<rdar://problem/16801456>.
It also uncovered some more cases where we weren't getting quite the
right semantics for factory-methods-as-initializers, which are also
fixed here.

The hack to get the LLVM build system to do what we want is to define a
custom build rule for "XYZ.o" and then add "XYZ" as a dummy source file
to the SOURCES variable, which the LLVM Makefile system uses. To make it
clear that something unusual is going on here, I've changed all existing
instances of this to use "XYZ.o" in SOURCES, rather than having that name
be derived from "XYZ.swift" or whatever.
The actual Swift source files go in SWIFT_SOURCES for the time being
(and possibly forever, since Swift sources will always be built together).

Since our build system isn't really set up to cope with
multi-sourcefile-modules, dump all Foundation support directly into
Foundation.swift

Because we're using a "brute-force" combination of conversion to
NSString and forwarding, this code will continue to work when String
is replaced by NewString. It may not be fast yet, but at least it
will flesh out the experience for Cocoa programmers
