Make the name lookup interfaces all take DeclNames instead of identifiers, and update the lookup caches of the various file units to index their members by both compound name and simple name. Serialized modules are keyed by identifiers, so as a transitional hack, do simple name lookup then filter the results by compound name.

These return placeholder text at the moment, but this enables us to can build
infrastructure that passes them around before the ReST parser is working.

Teach name lookup to find complete object initializers in its
superclass when the current class overrides all of the subobject
initializers of its direct superclass.
Clean up the implicit declaration of constructors, so we don't rely on
callers in the type checker doing the right thing.
When we refer to a constructor within the type checker, always use the
type through which the constructor was found as the result of
construction, so that we can type-check uses of inherited complete
object initializers. Fixed a problem with the creation of
OpenExistentialExprs when the base object is a metatype.
The changes to the code completion tests are an improvement: we're
generating ExprSpecific completion results when referring to the
superclass initializer with the same signature as the initializer
we're in after "super.".
Swift SVN r14551
These are the only kinds of decl that will actually have compound names in practice in the short term. Initializers can have selector pieces too, but cannot be referenced outside of a constructor call, so their AST names don't matter.

If an enum has no cases with payloads, make it implicitly Equatable and Hashable, and derive default implementations of '==' and 'hashValue'. Insert the derived '==' into module context wrapped in a new DerivedFileUnit kind, and arrange for it to be codegenned with the deriving EnumDecl by adding a 'DerivedOperatorDecls' array to NominalTypeDecls that gets visited at SILGen time.

A few improvements in our checking of property overrides:
* Properly check for an extraneous @override on a property
* Don't allow overriding of stored properties or with a stored property
* Only allow a covariant override when the overridden property is not mutable
* Check overrides as part of validation, not in a post-pass

- Respond to Doug's code review feedback
- Stop hacking around with scopes and use "emplace" to work around RAII in the inactive config case
- Limit use of StringRef on the front-end, in favor of std::string
- Use ArrayRef rather than SmallVector within IfConfigDecl
- Reorder new property declarations on BraceStmt to prevent unnecessary alignment issues
- Update ParseBraceItems to better capture top-level declarations, rather than using token lookahead

These changes add support for build and target configurations in the compiler.
Build and target configurations, combined with the use of #if/#else/#endif allow
for conditional compilation within declaration and statement contexts.
Build configurations can be passed into the compiler via the new '-D' flag, or
set within the LangOptions class. Target configurations are implicit, and
currently only "os" and "arch" are supported.

Emit vtable entries for abstract initializers. When we're constructing
an object using an abstract initializer based on a metatype value that
is not statically derivable, use the vtable entry to call the
subclass's allocating constructor.
Most of the IRGen work here is hacking around the lossy SILDeclRef ->
(Code|Function)Ref -> SILDeclRef conversion. I'd feel bad about this
if John hadn't already agreed to clean this up at some point.
Swift SVN r14238
This is more in line with all other modules currently on our system.
If/when we get our final name for the language, we're at least now set
up to rename the library without /too/ much trouble. (This is mostly just
a lot of searching for "import swift", "swift.", "'swift'", and '"swift"'.
The compiler itself is pretty much just using STDLIB_NAME consistently now,
per r13758.)

GenericSignatures with no params or requirements are a bug, so verify that they don't happen by making GenericSignature::get return null and GenericFunctionType assert that it has a nonnull signature. Hack Sema not to try to produce nongeneric GenericFunctionTypes when a function in a local type in a generic function context is type-checked; there's a deeper modeling issue that needs to be fixed here, but that's beyond the scope of 1.0. Now that GenericSignature always has at least one subtype, its factories no longer need an independent ASTContext argument.
Swift SVN r13837
Change GenericFunctionType to reference a GenericSignature instead of containing its generic parameters and requirements in-line, and clean up some interface type APIs that awkwardly returned ArrayRef pairs to instead return GenericSignatures instead.
Swift SVN r13807
For better type safety in SILFunctionTypes, which always want canonical types, and to provide a unique place to hang information common to all equivalent generic signatures, give GenericSignatures a concept of being "canonical".
Swift SVN r13794
Most of the complexity here is teaching SILGen how to handle closed-over direct
accesses to observing properties, since all of the getter/setter/willSet/didSet
members of the property are actually full closures when in a function body.
We generate correct but really terrible code here, since the setter captures the
willset/didset members themselves. I'm not worrying about the performance of
this construct though, functionality is what matters.
Swift SVN r13778
Have SILType::subst and SILFunctionType::subst always visit the interface types of a SILFunctionType. Fix up some problems in the specializer this exposed by having it correctly apply interface type substitutions to the function type of a specialized function and contextualized substitutions to the body.
Swift SVN r13714
SubscriptDecl is created, then the accessors are installed on it.
This allows us to create the subscript decl before the accessors
have been parsed, allowing us to build the subscript even in invalid
cases (better for later error recovery).
More importantly, this allows us to add it to Decls before calling
parseGetSet, so we can now make parseGetSet add accessors to Decls
without breaking source order (something that deeply upsets the IDE
features).
With all this untangled, we can now remove the 'addAccessorsInOrder'
hack where we parsed the accessors and then later tried to figure out
which order they came for the purpose of linking up the AST: accessors
now work just like everything else.
Swift SVN r13708
now that they are implicitly updated. This exposes two things:
1) we're unncessarily serializing selfdecls in ctors and dtors.
2) The index pattern of a SubscriptDecl has no sensible DeclContext that
owns variables in it.
I'll deal with the first tomorrow, I'm not sure what to do with
the second one.
Swift SVN r13703
all of their generic parameters. This simplifies logic creating them,
allowing us to eliminate all setDeclContext() calls from the parser.
While we're at it, change Parser::addVarsToScope to be a static
function in ParseStmt.cpp and dramatically cut it down since none of
its remaining clients are using most of its capabilities. It needs
to be simplified even further.
Swift SVN r13702
automatically reparent VarDecls in their arg/body patterns and
GenericParameters to themselves. These all have to be created
before the actual context decl is created and then reparented,
so we might as well have the reparenting be done by the decl
itself. This lets us take out some setDeclContext reparenting
loops from around the parser.
I'm sure that there are a lot more places they can be removed
from as well.

Refactor the base PolymorphicConvention implementation to work using generic signatures and dependent types instead of GenericParamLists and archetypes, using an ArchetypeBuilder to produce representative archetypes as a convenience when we need to consider all of the requirements attached to a dependent type. In EmitPolymorphicParameters, map the dependent types into context to resolve the archetypes that should be bound in the body of the function.
