214751e036 Allow variables with observers to still have inferred types.
Previously, adding observing accessors to a variable caused it to require
an explicit type /and/ an initializer. Now you just need one or the other;
the type of the accessors is drawn from the type of the VarDecl, whether
inferred or explicitly written.

b642c555be Allow one to change the argument labels of curried function parameters.
Curried function parameters (i.e., those past the first written
parameter list) default to having argument labels (which they always
have), but any attempt to change or remove the argument labels would
fail. Use the fact that we keep both the argument labels and the
parameter names in patterns to generalize our handling of argument
labels to address this problem.

The IDE changes are due to some positive fallout from this change: we
were using the body parameters as labels in code completions for
subscript operations, which was annoying and wrong.

Fixes rdar://problem/17237268.

fab3d491d9 Serialize local types and provide a lookup API
rdar://problem/18295292

Locally scoped type declarations were previously not serialized into the
module, which meant that the debugger couldn't reason about the
structure of instances of those types.

Introduce a new mangling for local types:
[file basename MD5][counter][identifier]
This allows the demangle node's data to be used directly for lookup
without having to backtrack in the debugger.

Local decls are now serialized into a LOCAL_TYPE_DECLS table in the
module, which acts as the backing hash table for looking up
[file basename MD5][counter][identifier] -> DeclID mappings.

New tests:
* swift-ide-test mode for testing the demangle/lookup/mangle lifecycle
of a module that contains local decls
* mangling
* module merging with local decls

cae0f6e3db Add the ability for a owning addressor to return
a non-native owner.  This is required by Slice, which
will use an ObjC immutable array object as the owner
as long as all the elements are contiguous.

As part of this, I decided it was best to encode the
native requirement in the accessor names.  This makes
some of these accessors really long; we can revisit this
if we productize this feature.

Note that pinning addressors still require a native
owner, since pinning as a feature is specific to swift
refcounting.

dc4431ebff Split addressors into unsafe, owning, and pinning variants.
Change all the existing addressors to the unsafe variant.

Update the addressor mangling to include the variant.

The addressor and mutable-addressor may be any of the
variants, independent of the choice for the other.

SILGen and code synthesis for the new variants is still
untested.

rdar://problem/17198298

- Allow 'static' in protocol property and func requirements, but not 'class'.
- Allow 'static' methods in classes - they are 'class final'.
- Only allow 'class' methods in classes (or extensions of classes)
- Remove now unneeded diagnostics related to finding 'static' in previously banned places.
- Update relevant diagnostics to make the new rules clear.

d0068877f5 [PGO] Add SILMetadata for branch weights.
SILMetadata is the base class with a single enum member (MDKind).
SILBranchNode is the derived class with additional members:
  unsigned NumOperands
  an array of uint32_t

A static member function SILBranchNode::get is implemented to get or create
SILBranchNode. All SILMetadata created are uniqued and saved in SILModule's
member variable:
  llvm::FoldingSet<SILMetadata> Metadatas

Usage of SILMetadta by SILInstruction is captured in SILModule's member variable:
  llvm::DenseMap<const SILInstruction *, SILMetadata *> MetadataStore
This is similar to LLVM's Metadata. Another option is to add a SILMetadata* to
SILInstruction. The disadvantage is the waste of space when we don't have PGO on.

This commit also enables parsing and printing of SILMetadata.

We add keyword sil_metadata to define SILMetadata:
  sil_metadata !0 = {"branch_weights", 3, 5}

For parsing, we add a map in SILModule
  llvm::DenseMap<unsigned, SILMetadata *> NumberedMetadata
that maps from ID to SILMetadata* to help matching usage of "!id" in SILFunction
with definition of "!id" in sil_metadata section.

For printing, we assign IDs to SILMetadata at SILModule scope, we then pass in
an optional argument of
  llvm::DenseMap<const SILMetadata *, unsigned> *MetadataMap
to SILFunction::print in order to get the ID of SILMetadata used in
SILInstruction.

Post-commit review will be appreciated.

ffbed6979d Fix for rdar://problem/18990358 (Fuzzing swift: Swift verifier crashes).
Having VarDecl created with IsStatic=false and then modifying it to true later seems 
fragile, e.g. in this bug this attribute was not properly set because of early-outs. 
In this patch I just moved code fixing VarDecl, but in future we should consider 
making this flag immutable and initializing it on creation.

8c303ef7a6 Representational changes towards get-and-mutableAddress
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.

99cc7603be Add an @inline(__always) function attribute.
This will let the performance inliner inline a function even if the costs are too high.
This attribute is only a hint to the inliner.
If the inliner has other good reasons not to inline a function,
it will ignore this attribute. For example if it is a recursive function (which is
currently not supported by the inliner).

Note that setting the inline threshold to 0 does disable performance inlining at all and in
this case also the @inline(__always) has no effect.

7aa62ce835 Add an inline(late) attribute
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.
