The ArrayType protocol is developed for NewArray is a good basis for
what we want, but the ability to create arrays without value semantics
is adding complexity but questionable value. It isn't clear that we can
usefully expose a type called SharedArray<T>, even internally, if it
ceases to be truly shared when one copy grows, and therefore has its
buffer reallocated. Therefore, leave the NewArray test with a
ArrayType2, a refinement of ArrayType, that adds the ability to report
on its value semantics.
If we really want the optimizations that can be had in a large-scale
mutation by first unique'ing the array and making mutations in-place
thereafter, we can fall back to operating on NativeArrayBuffer<T>
directly.

Turns out CMake's PRE_BUILD mode for custom commands doesn't work with the
Ninja or Makefile generators (not sure about Xcode). Just do it as part of
an earlier target instead.

Before this commit, RandomAccessIndex was a refinement of
NumericOperations, which forced it to support inappropriate operations
such as multiplication. Many obvious random-access index types can't
support multiplication (e.g. a StridedIndex adapter, which moves its
underlying index by N positions for each increment).
Along the way:
* the addition and subtraction operations on RandomAccessIndex were
renamed to advancedBy and distanceTo, which prevents nasty ambiguities
when a type conforms to both RandomAccessIndex and Integer, and allows
Index DistanceTypes to actually be signed integers even when the Index
is unsigned.
* Before this commit, using internal interfaces, it was possible to
request static checking without also getting dynamic checks when
static checking is impossible. Now the relationship between static
and dynamic checking is built into the core protocols.
* NumericOperations.swift was moved into IntegerArithmetic.swift.gyb,
correcting missing operators by generating them programmatically and
in preparation for renaming the protocol to something more appropriate
Fixes
<rdar://problem/16246927> RandomAccessIndex is over-constrained
and possibly:
<rdar://problem/15605729> Make all operators generic over
protocols (in particular, get NumericOperations done)

To support layering improvements, add an (optionally built) "essential
core" library containing the minimum set of files required just to link
successfully. Right now all those object files are linked again into
swift_stdlib_core; it would probably be better to link the essential
core into the core, but my CMake/Swift Driver fu is not strong enough
and this will at least help during development.
Along the way, removed the obsolete SwiftStdlibSources.txt file, as we
only have to support one build system now.

Remove all gyb-generated files and generate them automatically from .gyb
files. Rename the proof-of-concept UnsafeArray.swift.gyb back to
UnsafeArray.swift. Never forget to update the .gyb file or regenerate
again!

As part of this, have the standard library target be responsible for
symlinking Clang's headers into the resource directory, instead of the
compiler target. This makes sure the headers show up in all copies of
the build directory.
This brings our iOS testing closer to what Xcode will do, which will
hopefully avoid issues like <rdar://problem/16052579>.

- Int and UInt are now struct types backed by Builtin.Word. Previously they
were typealiases for Int64; Int and Int64 are now distinct types.
- Mangled names 'i' and 'u' are now Int and UInt. Int64 is mangled longhand.
- Word is a typealias for Int. It is expected to go away in the future.
- Builtin.Word is unchanged.
- CLong and CUnsignedLong are typealiases for Int and UInt.
- FixedPoint.swift is now FixedPoint32.swift and FixedPoint64.swift.
Reunifying these requires better builtins, especially for checked
conversions (rdar://15472770).
- Updated many tests, mostly because Int is no longer spelled Int64 in sil.
- One check was removed from test decl/operator/operators.swift
because it changed behavior when Int became a non-typealias
type (rdar://15934688).
