By beating the compiler into submission with a "bouncing through
non-methods" method, I have made it accept my crazed intention that
Array and friends should interoperate with all Sequences and
Collections! Filing <rdar://problem/16954833> to document the failure
of the method method.

This entry point is used when T is bridged verbatim and U is bridged
non-verbatim. It attempts to bridge each T from Objective-C to a U,
and returns nil if any of the elements cannot be bridged back to a U.
For now, only _convertNSArrayToArray and Array.bridgeFromObjectiveC
depend on this. It will soon be used for checked casts from, e.g.,
AnyObject[] to String[].
This is part of <rdar://problem/16952771> and general array bridging.

One of my recent type-checker changes starting passing all array
upcasts, including "bridged" ones like String[] -> AnyObject[],
through the library entry point _arrayUpCast, which is only meant for
class/ObjC existential types that are bridged verbatim.
Fixes part of <rdar://problem/16952238>; more cleanup to follow.

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>.

I suspect this can be made much better. It only
works for comparing Array<T> and Array<T>,
NativeArray<T> and NativeArray<T>, etc., not
NativeArray<T> and Array<T>. I also suspect
the implementation can be made better. The goal
was to make this functional, as this basic
functionality was missing.
Implements <rdar://problem/16768095>.

The old ones were:
- print/println
- printAny
- printf
- Console
The new printing story is just print/println. Every object can be printed.
You can customize the way it is printed by adopting Printable protocol. Full
details in comments inside stdlib/core/OutputStream.swift.
Printing is not completely finished yet. We still have ReplPrintable, which
should be removed, string interpolation still uses String constructors, and
printing objects that don't conform to Printable will result in printing
mangled names.
