with FuncDecls. This allows us to eliminate special case code for handling
self in various parts of the compiler.
This also improves loc info (debug info and AST info) because 'self' now
has a location instead of being invalid.
I also took the opportunity to factor a bunch of places creating self decls
to use similar patterns and less copy and paste code.

Allow IfStmts and WhileStmts to have as their condition either an expression, as usual, or a pattern binding introduced by 'var' or 'let', which will conditionally bind to the value inside an optional. Unlike normal pattern bindings, these bindings require an in-line initializer, which will be required to be Optional type. Parse variable bindings in this position, and type-check them by requiring an Optional on the right-hand side and unwrapping it to form the pattern type. Extend SILGen's lowering of if and while statements to handle conditionally binding variables.

Currently only inline functions referenced from Swift source files, or
from the REPL, will get IR generated for them. Inline functions
referenced by other inline functions will require additional effort to
generate properly.
With this change we use the clang::CodeGenerator-created llvm::Module
for all IR generation in Swift. This is perhaps undesirable, but
unavoidable given the interface the public Clang APIs expose, which do
not allow for building a ModuleBuilder that borrows an existing
llvm::Module.
Also unfortunate is the hack to generate a UsedAttr for each imported
inline function, but the public Clang APIs do not provide a way to only
emit deferred decls without emitting other things (e.g. module flags
that conflict with what the Swift IRGen emits). Note that we do not do
IRGen for every inline function in the module - only the ones that the
importer pulls in, which appears to be only those transitively
referenced from Swift code.

This is necessary on 32-bit arm, where va_list's canonical type is void*.
Without a typedef-based mapping the importer would drop declarations used
by the NSStringAPI bridge because they appear to have void* parameters.
This mapping does not work on x86_64. SwiftTypeConverter::VisitTypedefType()
never sees va_list on that architecture only, perhaps due to that
architecture's unusual definition of __builtin_va_list. The default mapping
to COpaquePointer plus the conversion CVaListPointer=>COpaquePointer
is still in place for that architecture.

Instead, just import them as a pair of methods. This is obviously suboptimal,
but better than the alternative in which you can see the property, but
attempting to use the accessor with the customized name results in a crash
at runtime.
Swift SVN r12755
This still isn't /that/ lazy because a lot of things can force member
deserialization (such as the type-checker generating a DestructorDecl for
every imported class), and we don't do this in a member-granular way just
yet. I don't see any change in testing time, for example.
But besides just being a good thing in general, this perturbs the order
of imported decls enough to fix <rdar://problem/15799697>: we can now
reliably see that there is a -URL:something: function on NSObject that
blocks any properties named 'URL' from being imported as properties.
(Which we don't actually want; see <rdar://problem/15456130>.)
Swift SVN r12685
Direct access to ivars is very rare in our frameworks, and they can conflict
with property names (which we should prefer). On top of that, we weren't
even emitting the right code to access them correctly.

with two kinds, and some more specific predicates that clients can use.
The notion of 'computed or not' isn't specific enough for how properties
are accessed. We already have problems with ObjC properties that are
stored but usually accessed through getters and setters, and a bool here
isn't helping matters.

-respondsToSelector: is declared on the NSObject protocol, which is adopted
by the NSObject root class. The NSObject metaclass also extends NSObject,
so it also needs a respondsToSelector:. This effectively becomes a
+respondsToSelector: method on NSObject-the-class.
Change importMirroredProtocolMembers to actually do this, just like
importObjCMembers was changed in r11614 for instance methods declared
directly within the class.
Finishes <rdar://problem/13371711>.

Rather than append the "Proto" suffix to all imported Objective-C
protocols, which can be confusing, whitelist those protocols that we
do have to rename. Only NSObject falls into this category so far.
Fixes <rdar://problem/15741699>.
Swift SVN r11856
This allows us to enable a verifier that ensures that protocol
conformances account for all requirements in the corresponding
protocol.
Swift SVN r11813
More specifically, instance methods on root objects are also class methods,
because the metatype for that class will inherit from the root class.
(That is, NSObject's metatype extends NSObject.)
This is necessary to allow calling, say, -respondsToSelector: on a class.
Unfortunately, it also brings in every other method on NSObject, including
"informal protocol" category methods like -awakeFromNib. We should probably
disprefer these in code completion, especially if they're declared in another
module, but it is perfectly legal to call these methods on Class objects in
Objective-C.

and check for CF_ENUM/CF_OPTIONS, which NS_ENUM/NS_OPTIONS expand to.
This:
- Simplifies code
- Handles CF_ENUM/CF_OPTIONS enums
- Handles correctly an NS_ENUM/NS_OPTIONS enum that was itself expanded from another macro.

We'll need to perform name lookup based on the file-level
DeclContext*, so the module no longer suffices. No functionality

ArraySliceType::get, OptionalType::get, and a few
other places.
There is more to be done here, but this is all I plan to do
for now.

This is a structural baby step toward lazily filling in protocol
conformances. We always build a ProtocolConformance, then mark it
either "complete" (when it's well-formed) or "invalid" (when it's
ill-formed). At present, the only benefit to this is that it slows
diagnostic cascades from invalid conformances.

typealias MyInt: ForwardIndex = Int
There is no real reason to allow this; it's just a static_assert that Int
conforms to ForwardIndex, which would be better spelled some other way.
This only applies to concrete typealiases, i.e. those that simply alias an
underlying type. Associated types can still have both inheritance clauses
and a (default) underlying type.
Swift SVN r11481
Until we can actually do the implementation work necessary to make 'if optionSetValue.Option {}' work, this is a reasonable affordance to allow the C 'if optionSetValue & .Option {}' pattern to work and bring us to parity with ObjC.
