that have both storage AND accessors are accessed by-default through
their accessors. This bit indicates that a specific MRE should access
the storage instead.
Use this new bit in the synthesized getter/setter for "StorageObjC"
properties (it will also be used for other things in the future).
This also teaches SILGen about it.
One interesting aspect of this representation is that it makes it trivial
to add some expression syntax for directly accessing a store+computed
property (e.g. ObjC properties, also someday didSet/willSet properties)
someday if we care. This would be analogous to the "self->ivar" syntax
in objc (vs self.ivar). No, we will not use "->" for this. :-)
NFC since this is the use is still hidden under the -enable-new-objc-properties
staging option.

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.
NFC.

1) Revert my change to give DeclContext a dump method, it confuses the debugger.
2) Refactor SILGen::requiresObjCPropertyEntryPoints out to
VarDecl::usesObjCGetterAndSetter.

Make the compiler fully support both UTF-8 and UTF-16 string
literals. A (standard-library-defined) string type (such as String)
that wants UTF-16 string literals should conform to the
BuiltinUTF16StringLiteralConvertible protocol; one that wants UTF-8
string literals should conform to the BuiltinStringLiteralConvertible
protocol.
Note that BuiltinUTF16StringLiteralConvertible inherits from
BuiltinStringLiteralConvertible, so a string type that wants UTF-16
string literals also has to implement support for UTF-8. The UTF-16
entry point is preferred when the compiler knows that UTF-16 is
supported. This only tends to happen when we have a generic parameter
that is required to conform to StringLiteralConvertible, e.g.,
func f<T: StringLiteralConvertible>() {
var t: T = "Hello, World!" // uses UTF-8 entry point
}
because the UTF-8 entry point is the only one guaranteed to be available.

A few places in the core compiler were referring to instances of the
Sequence protocol as "Containers". The "Indexable" protocol will soon
be renamed "Container," so eliminate this potential confusion

- mark closure arguments (both explicit and $0's) as immutable
- Adjust the stdlib (one place) and some tests to cope with this.
- Remove some special case logic in sema for lvalue qualifying
anonymous closure exprs, which is now the wrong thing to do.

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

It's useful to know what the open type variables in a generic protocol conformance are. For now, make the somewhat shaky assumptions that a NormalProtocolConformance for a bound generic type is for the DeclaredTypeInContext of its originating nominal type, that all type variables of the nominal type are open, and that specialized and inherited conformances bind all of the generic parameters.
Swift SVN r11274
are not settable (like get-only ones). Set the 'isLet' bit in various
places, but not the particularly interesting or useful places yet.

This prints the identifying info for a protocol conformance without the actual witness maps, recursively naming specialized or inherited conformances.

The goal of this series of commits is to allow the main module to consist
of both source files and AST files, where the AST files represent files
that were already built and don't need to be rebuilt, or of Swift source
files and imported Clang headers that share a module (because they are in
the same target).
Currently modules are divided into different kinds, and that defines how
decls are looked up, how imports are managed, etc. In order to achieve the
goal above, that polymorphism should be pushed down to the individual units
within a module, so that instead of TranslationUnit, BuiltinModule,
SerializedModule, and ClangModule, we have SourceFile, BuiltinUnit,
SerializedFile, and ClangUnit. (Better names welcome.) At that point we can
hopefully collapse TranslationUnit into Module and make Module non-polymorphic.
This commit makes SourceFile the subclass of an abstract FileUnit, and
makes TranslationUnit hold an array of FileUnits instead of SourceFiles.
To demonstrate that this is actually working, the Builtin module has also
been converted to FileUnit: it is now a TranslationUnit containing a single
BuiltinUnit.

This allows expressions such as ".foo" and ".foo(1)" to refer to
static variables and static methods, respectively, as well as enum
cases.
To get here, rework the parsing of delayed identifier expressions a
bit, so that the argument itself is part of the delayed argument
expression rather than a separate call expression. This simplifies
both the handling of patterns of this form and the type checker, which
can now user simpler constraints.
If we really want to support (.foo)(1), we can make that work, but it
seems unnecessary and perhaps confusing.
Swift SVN r10626
Handle the static var case in various places in the type-checker where it was assumed not to happen. For simplicity, build static var references as DeclRefs for now, with an assert to ensure we fix this before turning on potentially dynamic cases.
Swift SVN r10372
Similar to the T -> U? conversion, allow T? to be converted to U? through a bind-convert-inject chain. Naively adding this conversion creates ambiguities in the type checker, opening up multiple paths to the same solution in certain cases, so add a a special case to the solver that avoids introducing the conversion if a solution is already available by other means. (Doug figured out that part; thanks Doug!)
This still introduces a regression in test/Constraints/optional.swift, rendering a call ambiguous when overloaded on argument types. <rdar://problem/15367036>
