3a202f601e Handle cases where we're constructing an array of objects and the constructor has default arguments.

965f450d42 Introduce cleanup scopes for "if" statements in two places: 
- Outside the "if", to ensure that we destroy the condition variable
    at the end of the "if" statement rather than at the end of the
    block containing the "if" statement.
  - Inside the "then" and "else" branches, so that we emit then- or
    else-local cleanups at the end of the corresponding block when the
    block is not a compound statement.

To make adding these new cleanup scopes easier (and since
switch/do/while will all need the same treatment), added the
CleanupScope RAII object to introduce a new cleanup scope and make
sure it gets cleaned up.

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.

6c4d255bf3 Implement clang support for indirect branch and address of label 
using the new LLVM support for this.  This is temporarily hiding
behind horrible and ugly #ifdefs until the time when the optimizer
is stable (hopefully a week or so).  Until then, lets make it "opt in" :)

4bd90e53c2 Eliminate QualifiedDeclRefExpr, which captured the notion of a 
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g., 

  namespace N { int i; }
  int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

2bb5cb490c reimplement codegen for indirect goto with the following advantages: 
1. CGF now has fewer bytes of state (one pointer instead of a vector).
2. The generated code is determinstic, instead of getting labels in
   'map order' based on pointer addresses.
3. Clang now emits one 'indirect goto switch' for each function, instead
   of one for each indirect goto.  This fixes an M*N = N^2 IR size issue
   when there are lots of address-taken labels and lots of indirect gotos.
4. This also makes the default cause do something useful, reducing the
   size of the jump table needed (by one).

8ccfcb51ee Refactor the representation of qualifiers to bring ExtQualType out of the 
Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.
