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

Ultimately this gets to HeapBuffer which checks the index is in range by separately checking whether the storage is nil, then the index is less than the count

To facilitate the removal of the BooleanType conformance from Optional<T>, we'll first need to support
equality comparisons between the 'nil' literal and optionals with non-equatable element types.
We can accomplish this via three changes:
- New overloads for "==" and "!=" that we can resolve against non-equatable optionals
- A tweak to our overload resolution algorithm that, when all other aspects of two overloads are
considered equal, would favor the overload with a more "constrained" type parameter. This allows
us to avoid ambiguities between generic overloads that are distinct, but whose parameters do not
share a pairwise subtype relationship.
- A gross hack to favor overloads that do not require bindings to 'nil' when presented with an
otherwise ambiguous set of solutions. (Essentially, in the face of a potential ambiguity, favor solutions
that do not require bindings to _OptionalNilComparisonType over those that do.)
The third change is only necessary because we currently lack the ability to specify "negative" or
otherwise more expressive constraints, so we'll want to rethink the hack post-1.0. (I've filed
rdar://problem/17769974 to cover its removal.)

Lift the precondition that contiguous storage already exist on the use
of Array.withUnsafe[Mutable]PointerToElements. Automatically guarantee
that storage is unique when using the mutable variants of these methods.
Also, fix some---essentially---inout aliasing violations in
test/stdlib/Unicode.swift that were revealed by the new careful
implementation of these methods.

All .first() and .last() methods became T? vars that are nil when the

Arrays of non-verbatim-bridged types (such as Int, and today's String)
are converted to Objective-C lazily, with the objects created due to
element conversion being autoreleased when necessary.

Giving the invocation target proxy a type will be bogus when we turn on 'dynamic'. This breaks the NSUndoManager tests because we still can't work with lvalues through AnyObject. <rdar://problem/17755906>

This effectively reverts all but the NSRange part of r20241, because
it's better to have consistent behavior across the platforms than have
this feature on just one platform.

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.

The only interesting bit is that for stdlib/objc to build reliably, its
.o files all need to depend on the generated swiftmodule files for any
of its library dependencies. It looks like cmake treats
target_link_libraries as only implying a dependency between the
resulting libraries, and not the objects. For now, I've achieved this
by making the objects depend on the whole target (which includes
linking), but only the swiftmodule is actually necessary.

Even if the user supplies an ordering predicate that isn't a strict-weak
ordering, algorithms should not index beyond their bounds. Otherwise, a
use of withUnsafeMutableStorage for optimization purposes could easily
do an unsafe memory access.
This commit comments and tests our algorithms that require strict weak
orderings, and fixes safety problems in partition(). Most benchmarks
are unaffected, but the rewrite of partition produces a 27% speedup in
the Phonebook benchmark at -O3 and a 22% speedup at -Ofast.
Also, at -Ofast, QuickSort lost 6% and RC4 gained 6%. These benchmarks
were not noticeably affected at -O3
