Give us a way to formally represent autoreleases in SIL separate from autoreleased returns, allowing us to lifetime-extend inner pointer parameters the lazy way and hopefully clean up some asmname hacks in the stdlib implementation too.
Swift SVN r16632
This will represent the return convention of imported __attribute__((objc_returns_inner_pointer)) methods. Leave it unimplemented for now until we can autorelease things sanely.

Use this node to capture the argument name and its source location in
the AST. We're only building these in one place at the moment; the
rest will be updated soon.

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.

NFC. DeclRange is a range over DeclIterators, and is used rather than
ArrayRef<Decl*> to retrieve the members of a nominal type declaration
or extension thereof. The intent is to change the representation of
DeclRange next.

Before this fix, we can't deserialize any SILFunction with generic outer
parameters.
We do not have the decl associated with the generic parameter list at SIL level,
so instead of using a nullptr decl, we serialize the outer generic parameters
directly.

The on-disk hashtable is moving from clang to llvm. This updates some
consumers for the new path and namespace. I've also shortened the
make_range(data_begin(), data_end()) calls on the hash table to just
use data().

Factory initializers express an initializer that produces an object of
the given type, but is not inherited and not designated. Although they
have a syntactic form for presentation purposes (-> ClassName), there
is no way to specify or implement them within Swift. Rather, factory
initializers are created when importing an Objective-C factory method
that returns the class type rather than instancetype.
Swift SVN r16528
Convenience factory initializers are convenience initializers produced
by importing an Objective-C factory method as a convenience
initializer. The distinction is currently only used to eliminate the
awful layering violation I recently introduced in name lookup, which
was consulting Clang AST nodes directly. It will also be useful in
SILGen.
Swift SVN r16527
Introduce CtorInitializerKind to describe the kind of an enum, rather
than a bool, to make way for more initializer kinds in the future.
Swift SVN r16525
For BoundGenericType, we check if the generic arguments are Archetype and if the
Archetype appears in the Decl's Archetypes, if yes, we use indices into the
Decl's Archetypes instead of serializing the Archetype.
We add INT32_MAX as the first argument to notify the deserializer that the
arguments are indices into the Decl's Archetypes.
We also add a warning message when the Decl is serialized as a cross reference
and the generic arguments are serialized in this module.

Add project_block_storage, to project the capture storage from within a block_storage, and init_block_storage_header, to represent filling out the block header.
Swift SVN r16358
Blocks need to be born on the stack, so we need a way to represent that on-stack storage. @block_storage T will represent the layout of a block that contains storage for a capture of type T.

OnDiskIterableChainedHashTable interface introduced in CFE 206189.
Thanks to Justin for guiding me through this!
The test-failures I was worried about after I originally committed this
turned out to be unrelated.

We have to work with selectors quite often, so provide an efficient
representation for them. Switch ObjCAttr over to this representation,
which has the nice property that it efficiently represents implicit
@objc attributes with names and allows us to overwrite the Objective-C
name without losing all source information. Addresses
<rdar://problem/16478678>, and sets us up for dealing with selectors
better.
Swift SVN r16327
Entities with shared linkage are allowed to be discarded if they are unused even
in a library context.
Previously we implemented this in the serializer, which introduced
needless complications. Now we leave that responsibility to the optimizer giving
simplicity.

1. We call DEBUG() so we should set DEBUG_TYPE.
2. Print out the function name when printing out its abbrCode, bitno, etc.
3. Dump the SIL after printing the function information. This makes it easier to navigate the resulting output.
Swift SVN r16102
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.
