- Change the parser to accept "objc" without an @ sign as a contextual
keyword, including the dance to handle the general parenthesized case.
- Update all comments to refer to "objc" instead of "@objc".
- Update all diagnostics accordingly.
- Update all tests that fail due to the diagnostics change.
- Switch the stdlib to use the new syntax.
This does not switch all tests to use the new syntax, nor does it warn about
the old syntax yet. That will be forthcoming. Also, this needs a bit of
refactoring, which will be coming up.

optimization/inlining scheme.
It was actually used while building a release version of stdlib, and
effectively disabled safety checks in debug builds.

Allow a String value to be implicitly converted to ConstUnsafePointer<{UInt8,Int8,Void}> by string-to-pointer conversion, when enabled by a staging flag.
Swift SVN r19366
This applies to both qualified and unqualified lookups, and is controlled
by the -enable-access-control and -disable-access-control flags. I've
included both so that -disable-access-control can be put into specific tests
that will eventually need to bypass access control (e.g. stdlib unit tests).
The default is still -disable-access-control.
Swift SVN r19146
Add primitive type-checker rules for pointer arguments. An UnsafePointer argument accepts:
- an UnsafePointer value of matching element type, or of any type if the argument is UnsafePointer<Void>,
- an inout parameter of matching element type, or of any type if the argument is UnsafePointer<Void>, or
- an inout Array parameter of matching element type, or of any type if the argument is UnsafePointer<Void>.
A ConstUnsafePointer argument accepts:
- an UnsafePointer, ConstUnsafePointer, or AutoreleasingUnsafePointer value of matching element type, or of any type if the argument is ConstUnsafePointer<Void>,
- an inout parameter of matching element type, or of any type if the argument is ConstUnsafePointer<Void>, or
- an inout or non-inout Array parameter of matching element type, or of any type if the argument is ConstUnsafePointer<Void>.
An AutoreleasingUnsafePointer argument accepts:
- an AutoreleasingUnsafePointer value of matching element type, or
- an inout parameter of matching element type.
This disrupts some error messages in unrelated tests, which is tracked by <rdar://problem/17380520>.

This will enable via the -print-stats function the ability to quickly
find out the final count of various forms of instructions. My intention
is to use this to count retains and releases.
Swift SVN r18946
Allow class metatypes (including class-constrained existential metatypes) to be treated as subtypes of AnyObject, and single-@objc protocol metatypes to be treated as subtypes of the Protocol class from objc. No codegen support yet, so this is hidden behind a frontend flag for now.
Swift SVN r18810
This only works when swift is packaged with Xcode or installed as a command
line tool, but those are the important cases.

If we can't determine the type of an input file, we assume it's a linker
input of some sort (like Clang does). However, if we're not actually linking,
this resulted in unused inputs, which the driver choked on.
This commit updates the driver to throw away (and diagnose) inputs that
aren't going to be compiled if they aren't going to be used later on.
It also checks that none of our non-object output types are being treated
as linker inputs, since we do have that information around.

Previously, the frontend detected that its output was being piped into the
driver and buffered, and decided that that wasn't a color-friendly output
stream. Now, the driver passes -color-diagnostics to the frontend to force
color output if the driver itself is in a color-output context.

I didn't want to rip this logic out wholesale. There is a possibility
the character lexing can be reborn/revisited later, and
disabling it in the parser was easy.
Swift SVN r18102
This turns on bridging of Dictionary<K, V> by default
<rdar://problem/16870606>. The -objc-bridge-dictionary option remains
and currently means "import NSDictionary* as Dictionary<NSObject,
AnyObject>". We'll flip that switch separately.
Swift SVN r17855
If a temporary file is mentioned in the output map, it is also preserved.
We can make a nicer -save-temps later, but for now this will at least stop
leaving random files in /var/tmp.

This was originally intended for use with options that were processed by
the driver itself, rather than fed into other tools, but we weren't very
consistent about it and never actually used it for anything.
Swift SVN r17849
This option puts a special symbol into the generated object files that other
object files can reference to force the library to be loaded.
The next commit will modify the way we serialize autolinking information so
that importers of this module will always emit a reference to this symbol.
This means the library will be linked into the final binary even if no other
symbols are used (which happens for some of our overlays that just add
category methods to Objective-C classes).

When importing an Objective-C init method or factory method into an
initializer, if the first camelCase word of the first argument name
starts with "with", drop the "with". This means that
-initWithRed:green:blue:alpha:
will get imported into Swift as
init(red:green:blue:alpha:)
as will
+colorWithRed:green:blue:alpha:
This is <rdar://problem/16795899>, hidden behind the
-implicit-objc-with flag.

THIS IS NOT READY FOR USE YET.
The new plan for mixed-source non-framework targets is that the Swift
compiler will import an Objective-C header directly, and treat the decls
and imports in that header as explicitly visible to the entire target.
This means users don't have to modularize their headers before bringing
them into Swift.
This commit adds the option and introduces the "imported headers" module
as an implicit import for the source files being compiled. It also directs
the Clang importer to process the given header (using #import, so that it
won't somehow get included twice) and watches for any module imports that
occur as a result of reading that header.
Still to come: import of decls within the header (not within any module),
and proper serialization of cross-references to the header and its imports.

Another baby step toward <rdar://problem/14462349>, made even more
tepid by the fact that I've quarantined this behind a new flag,
-strict-keyword-arguments. Enforcing this breaks a lot of code, so I'd
like to bring up the new model on the side (with good diagnostics that
include Fix-Its) before trolling through the entire standard library
and testsuite to fix violations of these new rules.
Swift SVN r17143
Since LLDB is taking over as the REPL for Swift, we eventually want "swift"
and "swift -repl" to invoke "lldb --repl" rather than the frontend. However,
we only want to do this if the LLDB that's present is related to the Swift
that's present -- we don't want to invoke some random LLDB on the system
or in some other Xcode installation. Therefore, Swift searches for LLDB--
first next to the driver, then in the usr/bin/ outside of a toolchain--
before choosing to use it.
If the user just passes -repl and an LLDB is not found relative to the
driver, the existing "integrated" REPL will be launched instead.*
If the user passes -lldb-repl and an LLDB is not found relative to the
driver, one from the user's PATH will be chosen (like the linker).
The user can also pass -integrated-repl to get the existing behavior.
"swift -frontend -repl" always uses the integrated REPL.
* Since LLDB's not quite ready to be the REPL yet, "swift -repl" still
invokes the integrated REPL. "swift -repl -experimental-prefer-lldb" tests
the new behavior; this option will become the default (and the flag removed)
in <rdar://problem/16776719>.
