We discussed this morning and agreed that the best way to fix rdar://20680375
is to differentiate between printing testable interfaces and printing general
interfaces, where the former includes internal decls and the latter does not.
Also, we always print accessibility keywords to be consistent.

Requiring a variadic parameter to come at the end of the parameter
list is an old restriction that makes no sense nowadays, and which we
had all thought we had already lifted. It made variadic parameters
unusable with trailing closures or defaulted arguments, and made our
new print() design unimplementable.
Remove this restriction, replacing it with a less onerous and slightly
less silly restriction that we not have more than one variadic
parameter in a given parameter clause. Fixes rdar://problem/20127197.

Also, we always print accessibility keywords in the printed interfaces, so that users can differentiate public and
internal decls.

Represents a heap allocation containing a value of type T, which we'll be able to use to represent the payloads of indirect enum cases, and also improve codegen of current boxes, which generates non-uniqued box metadata on every allocation, which is dumb. No codegen changes or IRGen support yet; that will come later.
This time, fix a paste-o that caused SILBlockStorageTypes to get replaced with SILBoxTypes during type substitution. Oops.

I didn't add anything to the table, just made use of what was already there.
We have plenty of additional calls to getIdentifier that could probably benefit
from this kind of easy access as well.
This commit also removes FOUNDATION_MODULE_NAME and OBJC_MODULE_NAME from
Strings.h. Neither of these is likely to change in the future, and both
already have KnownIdentifiers equivalents in use.
No intended functionality change.

They appear out of order relative to other requirements, so do a cheesy linear scan to find the requirements that belong at each depth. This shouldn't be too bad since there are at most two depths in practice today. Fixes a parse_stdlib failure after enabling OptionSetType.
Swift SVN r28903
Modules occupy a weird space in the AST now: they can be treated like
types (Swift.Int), which is captured by ModuleType. They can be
treated like values for disambiguation (Swift.print), which is
captured by ModuleExpr. And we jump through hoops in various places to
store "either a module or a decl".
Start cleaning this up by transforming Module into ModuleDecl, a
TypeDecl that's implicitly created to describe a module. Subsequent
changes will start folding away the special cases (ModuleExpr ->
DeclRefExpr, name lookup results stop having a separate Module case,
etc.).
Note that the Module -> ModuleDecl typedef is there to limit the
changes needed. Much of this patch is actually dealing with the fact
that Module used to have Ctx and Name public members that now need to
be accessed via getASTContext() and getName(), respectively.

This can happen in witnesses, whose context archetypes are composed from the type-level archetypes of the witnessing type, and the method-level archetypes of the requirement. If you have something like:
protocol Foo {
func foo<T>(x: T)
}
struct Bar<T>: Foo {
func foo<U>(x: U)
}
Bar's witness to Foo.foo will end up with two archetypes named "T". Deal with this by having the SIL printer introduce a name mapping that disambiguates colliding archetypes. Refactor the SIL printer to do streaming through the SILPrinter itself, rather than directly on its ostream, so that we make sure it controls how subelements like types are printed, and it can pass the appropriate options down to the AST type printer. Fixes rdar://problem/20659406.

Now we bind the defer body into a ClosureExpr and emit it at the point of
the defer. At any exit points out of the controlled region, we emit a call
to the closure.
This should cover any problems where expressions cannot be emitted multiple times.
However, this is dramatically more complex than the obvious implementation, so I
hope this patch can be reverted.
Swift SVN r27767
If you want to make the parameter and argument label the same in
places where you don't get the argument label for free (i.e., the
first parameter of a function or a parameter of a subscript),
double-up the identifier:
func translate(dx dx: Int, dy: Int) { }
Make this a warning with Fix-Its to ease migration. Part of
rdar://problem/17218256.

The rule changes are as follows:
* All functions (introduced with the 'func' keyword) have argument
labels for arguments beyond the first, by default. Methods are no
longer special in this regard.
* The presence of a default argument no longer implies an argument
label.
The actual changes to the parser and printer are fairly simple; the
rest of the noise is updating the standard library, overlays, tests,
etc.
With the standard library, this change is intended to be API neutral:
I've added/removed #'s and _'s as appropriate to keep the user
interface the same. If we want to separately consider using argument
labels for more free functions now that the defaults in the language
have shifted, we can tackle that separately.

the printed interface.
Previously we printed the typechecked and uniqued requirements and the result was non-sensical.
Long-term the requirements will be preserved in a better form but for now print the requirements
and serialize them.

Change all uses of "do { ... } while <cond>" to use "repeat" instead.
Rename DoWhileStmt to RepeatWhileStmt. Add diagnostic suggesting change
of 'do' to 'repeat' if a condition is found afterwards.

Because of the @opened attr, they need to be parenthesized in some positions, particularly in opened existential metatypes like (@opened P).Type. This should fix the parse_stdlib validation tests.
