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)

Playgrounds want to present aggregate-like values with fixed children, such as structs and classes, differently from container-like values with variable amounts of children, like arrays and dictionaries, so add a property to Mirror that describes the disposition of the value being reflected.

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.

It's dead, Jim. Also remove 'ClassNameable' since we don't use it for anything.
Reapply r14647 now that John fixed the serialization issue that scuttled it last time.

In response to feedback from the Xcode team, change the 'IDERepresentable' type from a protocol into an enum with a limited set of tags, starting with 'Text' and 'Image' for now. In the ObjC mirror, if the ObjC object has a -debugQuickLookObject method, use it to get an object we can try to map to the enum.
Swift SVN r14632
For ObjC classes, use class_copyIvarList to walk the ivars, and produce the summary string using -debugDescription. Still to come:
- visiting the base class as a child, and
- calling -debugQuickLookObject to get the quicklook object. Still waiting on a final design for the IDERepresentation API.

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!

Now a "foo.bar.gyb" file in a list of sources gets automatically
processed through gyb to produce "foo.bar"
Renamed a simple .swift file in the stdlib (which needs a rename anyway)
to have a .gyb extension as a proof-of-concept.
To make this useful for our existing gyb files, we need to figure out
how to pass them the right arguments; that's coming next.

This will catch almost all module cache errors during compiler / stdlib
development, at the cost of slowing down rebuilds of the overlay modules
a bit.
