0865837327 Emit non-unique type metadata lazily in IRGen.
We no longer emit any unnecessary objects just because
you import Foundation/Cocoa/whatever, at least from
IRGen; SILGen still does a ton of useless extra work.

8adaab0233 Fold ExtInfo::isThin and ::isBlock into a "Representation" enum.
These bits are orthogonal to each other, so combine them into one, and diagnose attempts to produce a type that's both. Spot-fix a bunch of places this revealed by inspection that we would have crashed in SILGen or IRGen if blocks were be handled.

9f7dab725c Make the ASTContext parameter to MetatypeType::get optional for type-checked types.
We can just get it from the instance type, if the instance type has been fully initialized, which is the case except during parsing of type decls when the decls' own types are being formed.

f807249aa8 [deserialization] Store the mangled name of a SILWitnessTable on the instance itself.
The importance of this is that we will be able to use this name during
SIL serialization/deserialization to lookup partially deserialized
witness tables.

I left IRGen's original code alone until I can discuss with Joe/John
combining the logic together.

446a9bd4a7 Introduce CanType versions of the various "getXOrBoundGenericX"

BoundGenericType.)

ac64ab7c60 IRGen: Emit an OBJC_CLASS symbol for @objc classes.
LLVM doesn't have interior symbols as a first-class concept, so generate module inline asm that defines the OBJC_CLASS symbol relative to the Swift metadata symbol. To prevent our system linkers from considering this symbol as the start of a new object and breaking apart class metadata objects, put the class metadata object into a no_dead_strip section.

This isn't quite enough to get the OBJC_CLASS symbol to be available--the symbol appears to show up in the .o as an undefined symbol and stripped out of the .dylib. John is investigating with the backend and linker teams as to why this is the case.

f83f94d9d8 Support build and target configurations
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.

3d5d8fdc03 Resilience expansion is really an aspect of a SILDeclRef.
We should also remove it from IRGen's Explosion API; IRGen
should always use maximal explosion, and SILGen will tell us
whether or not we need to put that in memory somewhere.
But that can be a later commit.

b5af687b6d Emit and use vtable entries for abstract initializers.
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.

c21a293243 Lazily emit SILFunctions with non-external linkage.
rdar://13013457

'import Cocoa' is still generating a ton of unnecessary
global metadata, which causes some unused VWTs to be built,
but at least we no longer generate tons of useless global
functions.  At least, we don't in IR-gen --- we still do
all the SILGen work for them.

32cf8b3bac Preserve SIL function order in the parser and IRGen.
We're mostly not that bad about this right now, but lazy
emission is going to wreak havoc.

Note that SILGen itself doesn't really make very good decisions
about the order in which to emit functions, but step one
towards fixing that is actually respecting it.

7fd26d22d5 Serialization: Fix a couple of issues with serializing context params of generic SILFunctions.
- Parameterize maybeReadGenericParams' BitstreamCursor so that we can read from
  the correct cursor when trying to read the generic params of a SILFunction.
- Only serialize the context generic params for SILFunctions for which we're
  serializing a complete definition. This fixes issues with us getting the
  wrong archetypes forward-declared from references in other modules.

In this version of the patch, we adjust the deserialization point for the
generic param list to correctly come before we check if the SILFunction block
is empty, and we add a kludge to keep the JIT from crapping itself when it sees
the same transparent definition in multiple REPL lines' modules
<rdar://problem/16094902>.

The previous commit solves a problem this exposed at r14050 in inout deshadowing
that caused memory corruption when transparent functions were imported. This
should now be safe to commit.

0b2541b58f Rename the standard library to "Swift" (instead of "swift")
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.)

f5b85341a1 Expand out the "isComputed" property in AbstractStorageDecl to be an enum
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.

0776c4b6b8 SIL: Reorient function type lowering toward interface types.

3524a79fa0 Emit .cxx_destruct for destruction of ivars in Objective-C-derived classes.
The Objective-C runtime executes the .cxx_destruct method after the
last -dealloc has executed when destroying an object, allowing the
instance variables to remain live even after the subclass's
destructor/-dealloc has executed, which is important for memory
safety. This fixes the majority of <rdar://problem/15136592>.

Note that IRGenModule::getAddrOfIVarDestroyer() contains  an egregious
hack to find the ivar destructor SIL function via a linear
search. We need a better way to find SIL functions that we know exist,
because LinkEntity does not suffice.
