Anders Carlsson e828c36933 Add a special BuildVirtualCall that's going to be used for building calls to destructors. This is needed because when compiling:
struct A {
	virtual ~A();
};

void f(A* a) {
	delete a;
}

A's deleting destructor should be called.

Anders Carlsson 78cfaa9e56 Fix two bugs with temporaries:
1. For 

A f() {
	return A();
}

we were incorrectly calling the A destructor on the returned object.

2. For

void f(A);
void g() {
	A a;
	f(a);
}

we were incorrectly not calling the copy constructor.

Eli Friedman d7686ef31c Unify the codepaths used to verify base and member initializers for explicitly
and implicitly defined constructors.  This has a number of benefits:

1. Less code.

2. Explicit and implicit constructors get the same diagnostics.

3. The AST explicitly contains constructor calls from implicit default
constructors.  This allows handing some cases that previously weren't handled
correctly in IRGen without any additional code. Specifically, implicit default
constructors containing calls to constructors with default arguments are now
handled correctly.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4

Anders Carlsson b7f8f594f3 Implement basic code generation of constructor calls. We can now compile:
struct S {
S(int, int);
};

void f() {
S s(10, 10);
}

Daniel Dunbar 22a87f94a9 Pull COdeGenFunction::CreateStaticBlockVarDecl (just for creating the
global variable) out of GenerateStaticBlockVarDecl. 
 - No intended functionality change.
 - Prep for some mild cleanups and PR3662.

Douglas Gregor ffca3a21f1 Provide a new kind of iterator, the specific_decl_iterator, that
filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.

Eli Friedman c8a590dda3 Warning fixes to operator precedence warnings.
Someone should double-check that I didn't somehow break ObjC 
serialization; I think the change there actually changes the semantics.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.
