Rather than go through reentrant and problematic contortions to make Swift
work with the existing Instruments hooks, they agreed to just patch some
globals that we provide to get their logic to be activated.

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.

This is the simplest case to test the infrastructure for
adding/removing/fixing keyword arguments at the call site that don't
line up with the keyword arguments in a declaration. Baby steps toward
<rdar://problem/14462349>.

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>.

As part of this, use tail allocation to reduce the memory footprint of
TupleExprs. Use factory methods to make it easier to construct.
I'll be using this information in a follow-on patch. SourceKit
probably wants it as well.

We're going to need the parser again later, and we probably shouldn't be
hoping Clang's -fsyntax-only mode lines up with what we need to do anyway.

Make ObjC method partial applications go through a native-to-foreign thunk so that we properly handle bridging conversions in the resulting function value. Partial applications through dynamic lookup are still broken because they apparently go through a different path.

Someday we'll have time to disentagle the real mangler from the rest of the compiler. For now, this is a hack.
<rdar://problem/16671220> Add a simple mangler API just for handling "Module.ClassName" and "Module.ProtocolName" cases
Swift SVN r17066
Introduce a model where an argument name is a keyword argument if:
- It is an argument to an initializer, or
- It is an argument to a method after the first argument, or
- It is preceded by a back-tick (`), or
- Both a keyword argument name and an internal parameter name are
specified.
Provide diagnostics Fix-Its to clean up cases where the user is
probably confused, i.e.,
- "_ x: Int" -> "x: Int" where "x" would not have been a keyword
argument anyway
- "x x: Int" -> "`x: Int"
This covers the compiler side of <rdar://problem/16741975> and
<rdar://problem/16742001>.
Update the AST printer to print in this form, never printing just
a type for a parameter name because we're also going to adopt
<rdar://problem/16737312> and it was easier to move the tests once
rather than twice.
Standard library and test updates coming separately.

This option implicitly imports the Clang module with the same name as the
module being built into every source file in the module being built.
This will be used for mixed-source framework targets to give Swift code the
same implicit visibility for Objective-C decls in the same module that it
already has for other Swift decls.

// IBAction, OS X:
@IBAction func foo(sender: AnyObjCClassCompatibleType?)
// IBAction, iOS:
@IBAction func foo()
@IBAction func foo(sender: AnyObjCClassCompatibleType?)
@IBAction func foo(sender: AnyObjCClassCompatibleType?, event: UIEvent?)
All argument types may be unchecked-optional or non-optional as well.
This commit doesn't check that the second argument to an iOS action method
is a UIEvent; the user may want to declare it as AnyObject or perhaps some
other protocol, so I just left it unenforced.
I'm also drawing on my knowledge of Cocoa to disallow String as an IBAction
parameter. Array and Dictionary also shouldn't appear here and thus don't
need special-casing even when bridged.

Set a bit for types that are non-bitwise-takable, and calculate it as part of runtime struct and enum layout. Include 'bitwise takable' as part of the runtime 'is inline' calculation to be consistent with the compile-time policy change in r17008.

double-quoted string literals that contain a single extended grapheme cluster
SEGCL by default infer type String, but you can ask to infer Character
for them.
Single quoted literals continue to infer Character.
Actual extended grapheme cluster segmentation is not implemented yet,

Building on previous work, this allows us to properly handle things like Int?() and Int[]().
Of course doing this exposed that TypeExpr was not correct in lots of ways, so this also:
- Revamps TypeExpr processing to carry a decl in the TypeLoc instead of
carrying a Type. This allows us to correctly handle more complex generics case.
- Enhances CSGen to properly open generic types so we can infer generic type parameters from
context.

Add Builtin.destroyArray, .copyArray, .takeArrayFrontToBack, and .takeArrayBackToFront, which perform bulk destroy/copy/take operations using memcpy/memmove, a loop, or a generic value witness.

Part of <rdar://problem/16742001>. At the moment, this is just a
parsing thing, because argument names are still API by default
anyway.
