Douglas Gregor d3f48bd3be Introduce a new libclang function,
clang_getSpecializedCursorTemplate(), which determines the template
(or member thereof) that the given cursor specializes or from which it
was instantiated. This routine can be used to establish a link between
templates and their instantiations/specializations.

Douglas Gregor a9aa29cf0b Implement libclang support for using declarations. Clang actually uses
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
  - Cursor visitation of the three AST nodes for using declarations
  - Proper source-range computation for these AST nodes
  - Using declarations have no USRs, since they don't actually declare
    any entities.

in a few related ways:

  - Don't recurse into instantiations of templates.
  - Recurse into explicit specializations.

    explicit instantiation.
  - Include template specialization arguments in the USRs for class
    template specializations.

Ted Kremenek 0ef508d301 Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols
(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration.  'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions.  The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

Fixes <rdar://problem/8380046>.

Chris Lattner d426c8eae3 fix rdar://8360877 a really nasty miscompilation in Boost.Xpressive
caused by my ABI work.  Passing:

struct outer {
  int x;

  int f;
};

as {i32,i32} isn't safe, because the offset of the second element
needs to be at 8 when it is interpreted as a memory value.

Douglas Gregor f9e43cef54 Improve location information in the representation of namespace
aliases. Previously, the location of the alias was at the "namespace"
keyword. Now, it's on the identifier being declared (as is the custom
for Clang), and we keep a separate source location for the "namespace"
keyword.

Also, added a getSourceRange() member function to NamespaceAliasDecl
to correctly compute the source range.

Finally, removed a bunch of setters from NamespaceAliasDecl and gave
ASTReaderDecl friendship so that it could set the corresponding fields
directly.

Douglas Gregor a89314e396 Add libclang support for namespace aliases (visitation + USRs) along

source locations displayed in the load-namespaces.cpp test will

within a template.

Douglas Gregor 4afc236cee When instantiating a function type, instantiate the return type before
instantiating the parameters. In a perfect world, this wouldn't
matter, and compilers are free to instantiate in any order they
want. However, every other compiler seems to instantiate the return
type first, and some code (in this case, Boost.Polygon) depends on
this and SFINAE to avoid instantiating something that shouldn't be
instantiated.

We could fight this battle, and insist that Clang is allowed to do
what it does, but it's not beneficial: it's more predictable to
instantiate this way, in source order. When we implement
late-specified return types, we'll need to instantiate the return type
last when it was late-specified, hence the FIXME.

We now compile Boost.Polygon properly.

specialization of a member template of a class template that itself is
a member template of another class template.

John McCall 8d08b9b408 Propagate whether an id-expression is the immediate argument of
an '&' expression from the second caller of ActOnIdExpression.

Teach template argument deduction that an overloaded id-expression
doesn't give a valid type for deduction purposes to a non-static
member function unless the expression has the correct syntactic
form.

Teach ActOnIdExpression that it shouldn't try to create implicit
member expressions for '&function', because this isn't a        
permitted form of use for member functions.

Teach CheckAddressOfOperand to diagnose these more carefully.
Some of these cases aren't reachable right now because earlier
diagnostics interrupt them.

Chris Lattner 9f8b451876 Finally pass "two floats in a 64-bit unit" as a <2 x float> instead of
as a double in the x86-64 ABI.  This allows us to generate much better
code for certain things, e.g.:

_Complex float f32(_Complex float A, _Complex float B) {
  return A+B;
}

Used to compile into (look at the integer silliness!):

_f32:                                   ## @f32
## BB#0:                                ## %entry
	movd	%xmm1, %rax
	movd	%eax, %xmm1
	movd	%xmm0, %rcx
	movd	%ecx, %xmm0
	addss	%xmm1, %xmm0
	movd	%xmm0, %edx
	shrq	$32, %rax
	movd	%eax, %xmm0
	shrq	$32, %rcx
	movd	%ecx, %xmm1
	addss	%xmm0, %xmm1
	movd	%xmm1, %eax
	shlq	$32, %rax
	addq	%rdx, %rax
	movd	%rax, %xmm0
	ret

Now we get:

_f32:                                   ## @f32
	movdqa	%xmm0, %xmm2
	addss	%xmm1, %xmm2
	pshufd	$16, %xmm2, %xmm2
	pshufd	$1, %xmm1, %xmm1
	pshufd	$1, %xmm0, %xmm0
	addss	%xmm1, %xmm0
	pshufd	$16, %xmm0, %xmm1
	movdqa	%xmm2, %xmm0
	unpcklps	%xmm1, %xmm0
	ret

and compile stuff like:

extern float _Complex ccoshf( float _Complex ) ;
float _Complex ccosf ( float _Complex z ) {
 float _Complex iz;
 (__real__ iz) = -(__imag__ z);
 (__imag__ iz) = (__real__ z);
 return ccoshf(iz);
}

into:

_ccosf:                                 ## @ccosf
## BB#0:                                ## %entry
	pshufd	$1, %xmm0, %xmm1
	xorps	LCPI4_0(%rip), %xmm1
	unpcklps	%xmm0, %xmm1
	movaps	%xmm1, %xmm0
	jmp	_ccoshf                 ## TAILCALL

instead of:

_ccosf:                                 ## @ccosf
## BB#0:                                ## %entry
	movd	%xmm0, %rax
	movq	%rax, %rcx
	shlq	$32, %rcx
	shrq	$32, %rax
	xorl	$-2147483648, %eax      ## imm = 0xFFFFFFFF80000000
	addq	%rcx, %rax
	movd	%rax, %xmm0
	jmp	_ccoshf                 ## TAILCALL


There is still "stuff to be done" here for the struct case,
but this resolves rdar://6379669 - [x86-64 ABI] Pass and return 
_Complex float / double efficiently
