Conforming to BooleanLiteralConvertible now requires
init(booleanLiteral: Bool)
rather than
static func convertFromBooleanLiteral(value: Bool) -> Self
This posed a problem for NSNumber's conformance to
BooleanLiteralConvertible. A class needs a required initializer to
satisfy an initializer requirement, but one cannot add a required
initializer via an extension. To that end, we hack the Clang importer
to import NSNumber's initWithBool with the name
init(booleanLiteral:)
and add back the expected init(bool:) initializer in the
overlay. These tricks make NSNumber even harder to subclass, but we
don't really care: it's nearly impossible to do well anyway, and is
generally a Bad Idea.

it indirectly through another pointer from Decl, just embed DeclAttributes
directly into Decl and get rid of the "getMutableAttrs" nonsense.

Introduce the new BooleanLiteralConvertible protocol for Boolean
literals. Take "true" and "false" as real keywords (which is most of the
reason for the testsuite churn). Make Bool BooleanLiteralConvertible
and the default Boolean literal type, and ObjCBool
BooleanLiteralConvertible. Fixes <rdar://problem/17405310> and the
recent regression that made ObjCBool not work with true/false.

No validation is done yet on whether the user-specified access control makes
sense in context, but all ValueDecls should at least /have/ accessibility now.
/Still/ no tests yet. They will be much easier to write once we're actually
enforcing access control and/or printing access control.

As part of this, use tail allocation to reduce the memory footprint of
TupleExprs. Use factory methods to make it easier to construct.
I'll be using this information in a follow-on patch. SourceKit
probably wants it as well.

As a step on the way to harmony with Cocoa, change Hashable's hashValue into a property requirement, and update the derived conformance generation to produce a computed property instead of a standalone function.
This is mostly Ted's patch, with some help from Dmitri to clean up the IDE aspects.

improves location information to track the label location in the AST. We
don't currently track the location of the colon, but that would be trivial
to drop in if it is interesting.

The use of ASTContext-allocated arrays to store the members of nominal
type declarations and the extensions thereof is an
abomination. Instead, introduce the notion of an "iterable"
declaration context, which keeps track of the declarations within that
context (stored as a singly-linked list) and allows iteration over
them. When a member is added, it will also make sure that the member
goes into the lookup table for its context immediately.
This eliminates a ton of wasted memory when we have to reallocate the
members arrays for types and extensions, and moves us toward a much
more sane model. The only functionality change here is that the Clang
importer no longer puts subscript declarations into the wrong class,
nor does it nested a C struct within another C struct.

In Sema, give derived '==' definitions the module's DerivedFileUnit as their decl context instead of the more general Module, and give it a backreference to the nominal type for which it was derived.
In SILGen, visit the derived global decls associated with Clang-imported enums, and give them shared linkage. Part of fixing <rdar://problem/16264703>.

This names the implicit argument "oldValue". Whether we keep implicit arguments or not
is a subject of debate, tracked by rdar://16268361.
Swift SVN r14819
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.
