3dbd6ea9bd InstrProf: SILFunction doesn't live long enough for SILCoverageMap
Keeping a reference to the function here is dangerous. We only
actually care about the name, so save ourselves a copy of that
instead.

This fixes a crash that seems to happen only when the coverage data is
very large.

fee103c42c Reapply two tweaks to if/let handling:
two logically independent but related patches conflated together: 
 - Improve error recovery for malformed if/let conditions, particularly 
   when the user uses "," instead of &&. Add testcases for error recovery 
   requested by Jordan.

- Add a syntactic requirement that the pattern of an if/let condition be 
  a simple identifier or _. We allow slightly broader patterns here now, 
  but they will change in the future when refutable patterns are allowed. 
  It is best to be narrow and then open it up later so we can do a great
  job of QoI then.

This includes the changes to the stdlib directory that I forgot to commit
with the patch the previous time.

db421806e2 fix <rdar://problem/19772570> Parsing of as and ?? regressed
In r22669, we expanded our parsing of T?? by using operator splitting.  This works
great when the ?? is lexed as a postfix operator, but does the wrong thing when the ??
is lexed as an infix  and there is whitespace around it.  For that, we don't want to 
process it as a type.  This was reported in a number of places including on stack
overflow:

fac5a83bbf Allow capturing super in explicit closures and nested functions.
The previous commit enabled this; now it's just about removing the
restriction in the parser and tightening up code completion.

Using 'super' in a closure where 'self' is captured weak or unowned still
doesn't work; the reference to 'self' within the closure is treated as
strong regardless of how it's declared. Fixing this requires a cascade of
effort, so instead I just cloned rdar://problem/19755221.

Before if you had a differing number of arguments from types, you would

c81cf86181 implement <rdar://problem/19707366> QoI: @autoclosure declaration change fixit
Before we would produce (with no fixit):

a.swift:1:13: error: attribute can only be applied to declarations, not types
let step : @autoclosure() -> () 
            ^

now we produce (with a fixit):

let step : @autoclosure() -> ()

6a70bd085e These changes implement some oft-requested tweaks and fixes to our closure implementation:
- Closures that are comprised of only a single return statement are now considered to be "single expression" closures. (rdar://problem/17550847)
- Unannotated single expression closures with non-void return types can now be used in void contexts. (rdar://problem/17228969)
- Situations where a multi-statement closure's type could not be inferred because of the lack of a return-type annotation are now properly diagnosed. (rdar://problem/17212107)

I also encountered a number of crashers along the way, which should now be fixed.

51f8070abe Serialize local types
Local type declarations are saved in the source file during parsing,
now serialized as decls. Some of these may be defined in DeclContexts
which aren't Decls and previously weren't serialized. Create four new
record kinds:

* PatternBindingInitializer
* DefaultArgumentInitializer
* AbstractClosureExpr
* TopLevelCodeDecl

These new records are used to only preserve enough information for
remangling in the debugger, and parental context relationships.

Finally, provide a lookup API in the module to search by mangled name.
With the new remangling API, the debugging lifecycle for local types
should be complete.

The extra LOCAL_CONTEXT record will compressed back down in a
subsequent patch.

Allows same-type constraints that map down to tuple types. This is a
minimal fix that allows the code in rdar://problem/18120419 to
type-check. However, the actual code in that radar triggers a SILGen
assertion (Archetype to be substituted must be valid in function), and
we're not recursively matching concrete types the way we should be, so
this is a baby step.

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.

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.

03a6190a1f <rdar://problem/19031957> Change failable casts from "as" to "as!"
Previously the "as" keyword could either represent coercion or or forced
downcasting. This change separates the two notions. "as" now only means
type conversion, while the new "as!" operator is used to perform forced
downcasting. If a program uses "as" where "as!" is called for, we emit a
diagnostic and fixit.

Internally, this change removes the UnresolvedCheckedCastExpr class, in
favor of directly instantiating CoerceExpr when parsing the "as"
operator, and ForcedCheckedCastExpr when parsing the "as!" operator.
