also, dump a bunch of other init() functions from other types.

Primarily, this means becoming resilient to Builtin.strideof(x) == 0.
Pretty much the only way to get pointers and arrays to make sense is to
treat zero-sized elements as having a stride of 1, so we do that in our
wrapper for Builtin.strideof. Other points include precondition checks
for radixes in number formatting.

Foundation, and have them forward to Foundation.
This is slower than it could be, but at least this way we produce correct
results.

As before, there may be more things marked @public than we actually want
public. Judicious use of the frontend option -disable-access-control may
help reduce the public surface area of the stdlib.

This one shows the unfortunate consequence that we need
Lazy[Forward|Bidirectional|RandomAccess]Collection. There's gonna be a
whole lotta gyb'bing going on...

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.

This is motivated by <rdar://problem/17051606>.
This ends up renaming variables as well, which seems right for
consistency since we use "predicate" as variable name.

In UTF-8 decoder:
- implement U+FFFD insertion according to the recommendation given in the
Unicode spec. This required changing the decoder to become stateful, which
significantly increased complexity due to the need to maintain an internal
buffer.
- reject invalid code unit sequences properly instead of crashing rdar://16767868
- reject overlong sequences rdar://16767911
In stdlib:
- change APIs that assume that UTF decoding can never fail to account for
possibility of errors
- fix a bug in UnicodeScalarView that could cause a crash during backward
iteration if U+8000 is present in the string
- allow noncharacters in UnicodeScalar. They are explicitly allowed in the
definition of "Unicode scalar" in the specification. Disallowing noncharacters
in UnicodeScalar prevents actually using these scalar values as internal
special values during string processing, which is exactly the reason why they
are reserved in the first place.
- fix a crash in String.fromCString() that could happen if it was passed a null
pointer
In Lexer:
- allow noncharacters in string literals. These Unicode scalar values are not
allowed to be exchanged externally, but it is totally reasonable to have them
in literals as long as they don't escape the program. For example, using
U+FFFF as a delimiter and then calling str.split("\uffff") is completely
reasonable.
This is a lot of changes in a single commit; the primary reason why they are
lumped together is the need to change stdlib APIs to account for the
possibility of UTF decoding failure, and this has long-reaching effects
throughout stdlib where these APIs are used.

It is replaced by debugPrint() family of functions, that are called by REPL.
There is a regression in printing types that don't conform to Printable, this
is tracked by rdar://16898708
Swift SVN r18006
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.
