... for the fully annotated declarations. More substructure more better.
This has to go through a callback mechanism similar to printDeclLoc and
printDeclPre since it should be scheduled after both of those are
printed.

Similarly to how we've always handled parameter types, we
now recursively expand tuples in result types and separately
determine a result convention for each result.
The most important code-generation change here is that
indirect results are now returned separately from each
other and from any direct results. It is generally far
better, when receiving an indirect result, to receive it
as an independent result; the caller is much more likely
to be able to directly receive the result in the address
they want to initialize, rather than having to receive it
in temporary memory and then copy parts of it into the
target.
The most important conceptual change here that clients and
producers of SIL must be aware of is the new distinction
between a SILFunctionType's *parameters* and its *argument
list*. The former is just the formal parameters, derived
purely from the parameter types of the original function;
indirect results are no longer in this list. The latter
includes the indirect result arguments; as always, all
the indirect results strictly precede the parameters.
Apply instructions and entry block arguments follow the
argument list, not the parameter list.
A relatively minor change is that there can now be multiple
direct results, each with its own result convention.
This is a minor change because I've chosen to leave
return instructions as taking a single operand and
apply instructions as producing a single result; when
the type describes multiple results, they are implicitly
bound up in a tuple. It might make sense to split these
up and allow e.g. return instructions to take a list
of operands; however, it's not clear what to do on the
caller side, and this would be a major change that can
be separated out from this already over-large patch.
Unsurprisingly, the most invasive changes here are in
SILGen; this requires substantial reworking of both call
emission and reabstraction. It also proved important
to switch several SILGen operations over to work with
RValue instead of ManagedValue, since otherwise they
would be forced to spuriously "implode" buffers.
This splits the printDeclNamEndLoc callback into NameEndLoc and
NameOrSignatureEndLoc variants to differentiate whether or not
signatures are included. All existing clients move to
NameOrSignatureEndLoc to maintain the current behaviour. I'm still not
completely happy with how these are named, but I dont' have any better
ideas right now.

Introduce a new attribute, swift3_migration, that lets us describe the
transformation required to map a Swift 2.x API into its Swift 3
equivalent. The only transformation understood now is "renamed" (to
some other declaration name), but there's a message field where we can
record information about other changes. The attribute can grow
somewhat (e.g., to represent parameter reordering) as we need it.
Right now, we do nothing but store and validate this attribute.
Allow all keywords except for parameter introducers (var/let/inout) to
be argument labels when declaring or calling a
function/initializer/subscript, e.g., this
func touchesMatching(phase: NSTouchPhase, `in` view: NSView?) -> Set<NSTouch>
can now be expressed as
func touchesMatching(phase: NSTouchPhase, in view: NSView?) -> Set<NSTouch>
and the call goes from
event.touchesMatching(phase, `in`: view)
to
event.touchesMatching(phase, in: view)
Fixes [SR-344](https://bugs.swift.org/browse/SR-344) /
rdar://problem/22415674.
When users try to print the interface of a specific type (most often through cursor
infor query of SourceKit), we should simplify the original decls by replacing
archetypes with instantiated types, hiding extension details, and omitting
unfulfilled extension requirements. So the users can get the straight-to-the-point
"type interface". This commit builds the testing infrastructure for this feature,
and implements the first trick that wraps extension contents into the interface body.
This commit also moves some generic testing support from SourceKit to Swift.

Cleans up AST printing somewhat as well as providing slightly better
type-to-declaration mappings for annotated AST printing and indexing.

This lets us reliably print and parse opened archetypes across different compiler invocations. Using a source-related locator would be ideal, but that's complicated by the need to manufacture, print, and parse these things during SIL passes, so cop out and burn a UUID for now.

When a subclass is missing a required initializer, produce an error
within the subclass that mentions the required initializer along with
a Fix-It that provides an initializer stub, e.g.,
required init(coder aDecoder: NSCoder!) {
fatalError("init(coder:) has not been implemented")
}
We take care to insert this stub in the main class, after all of the
initializers (if there are any) or near the beginning of the class (if
there aren't any initializers), and try to match the existing
indentation. If this works out, we should handle unsatisfied protocol
requirements the same way. <rdar://problem/17923210>

refactoring, allowing ASTPrinter callbacks to be called exactly when a first
non-whitespace character of the declaration is printed, ignoring the
indentation and leading blank lines.
