Modeling builtins as first-class function values doesn't really make sense because there's no real function value to emit, and modeling them this way complicates passes that work with builtins because they have to invent function types for builtin invocations. It's much more straightforward to have a single instruction that references the builtin by ID, along with the type information for the necessary values, type parameters, and results, so add a new "builtin" instruction that directly represents a builtin invocation. NFC yet.

properties.
The main design change here is that, rather than having
purportedly orthogonal storage kinds and has-addressor
bits, I've merged them into an exhaustive enum of the
possibilities. I've also split the observing storage kind
into stored-observing and inherited-observing cases, which
is possible to do in the parser because the latter are
always marked 'override' and the former aren't. This
should lead to much better consideration for inheriting
observers, which were otherwise very easy to forget about.
It also gives us much better recovery when override checking
fails before we can identify the overridden declaration;
previously, we would end up spuriously considering the
override to be a stored property despite the user's
clearly expressed intent.

I can't actually reproduce the buildbot failure that happened last night, so
hopefully it will (a) happen again, so I can investigate, or (b) not happen
again.

Doug had changed the comment but not the implementation -- we were still
serializing the containing module rather than the declaring nominal or
extension.
Found by enabling verification on deserialized decls (to come soon).

We add two more fields to SILGlobalVariable: a VarDecl and a flag to see if this
is a declaration. VarDecl is mainly used for debugger support, it is also used
to check if the variable is weak imported.
We also modify the serializer to serialize the extra two fields.

This behaves like @UIApplicationMain, except for AppKit. Attach it to your NSApplicationDelegate, and an artificial "main" will be generated that invokes NSApplicationMain() for you. Implements rdar://problem/16904667.

Previously, we depended on whether or not a serialized module was located
within a framework bundle to consider whether or not it may have a "Clang
half". However, LLDB loads serialized modules from dSYM bundles. Rather
than try to figure out if such a module is "really" a framework, just track
whether the original module was built with -import-underlying-module. If so,
consider the underlying Clang module to be re-exported.

Introduce an attribute that describes when a given CF type is
toll-free-bridged to an Objective-C class, and which class that
is. Use that information in the type checker to provide the CF <->
Objective-C toll-free-bridged conversions directly, rather than using
the user-defined conversion machinery.

This disables inlining at the SIL level. LLVM inlining is still enabled. We can
use this to expose one function at the SIL level - which can participate in
dominance based optimizations but which is implemented in terms of a cheap check
and an expensive check (function call) that benefits from LLVM's inlining.
Example:
The inline(late) in the example below prevents inlining of the two checks. We
can now perform dominance based optimizations on isClassOrObjExistential.
Without blocking inlining the optimizations would apply to the sizeof check
only and we would have multiple expensive function calls.
@inline(late)
func isClassOrObjExistential(t: Type) -> Bool{
return sizeof(t) == sizeof(AnyObject) &&
swift_isClassOrObjExistential(t)
}
We do want inlining of this function to happen at the LLVM level because the
first check is constant folded away - IRGen replaces sizeof by constants.

This allows UnicodeScalars to be constructed from an integer, rather
then from a string. Not only this avoids an unnecessary memory
allocation (!) when creating a UnicodeScalar, this also allows the
compiler to statically check that the string contains a single scalar
value (in the same way the compiler checks that Character contains only
a single extended grapheme cluster).

Previously, we only retained the module in which a normal protocol
conformance occurred, which meant we either had to go searching for
the appropriate extension (yuck) or do without that information. This
is part of the separating-extension-archetypes work.

Squash _[Conditionally]BridgedToObjectiveC into one protocol. This
change results in simpler bridging code with fewer dynamic protocol
conformance checks, and solves the nasty naming/semantics problem that
resulted from having _ConditionallyBridgedToObjectiveC refining
_BridgedToObjectiveC.
Also, rename things so they're more symmetrical and less confusing.

Previously, we were just storing setter accessibility via the accessibility
level on the setter function. However, some Stored properties never actually
have a setter synthesized, which led to the compiler dropping the setter
accessibility at serialization time. Rather than try to hack up something
clever, just store the setter accessibility explicitly in every
AbstractStorageDecl. (We still only serialize it for VarDecls, because
settable SubscriptDecls always have setter functions.)
