Allow lookup into dependent bases in more places under -fms-compatibility

We currently allow unqualified lookup for instance methods but not
static methods because we can't recover with a semantic 'this->'
insertion.

ATL headers have static methods that do unqualified lookup into
dependent base classes.  The pattern looks like:

  template <typename T> struct Foo : T {
    static int *getBarFromT() { return Bar; }
  };

Now we recover as if the user had written:

  template <typename T> struct Foo : T {
    static int *getBarFromT() { return Foo::Bar; }
  };

... which will eventually look up Bar in T at instantiation time.

Now we emit a diagnostic in both cases, and delay lookup in other
contexts where 'this' is available and refers to a class with dependent
bases.

[PPC64LE] Implement little-endian semantics for vec_sums

The PowerPC vsumsws instruction, accessed via vec_sums, is defined
architecturally with a big-endian bias, in that the second input vector
and the result always reference big-endian element 3 (little-endian
element 0).  For ease of porting, the programmer wants elements 3 in

the second input vector prior to the vsumsws instruction, and generate
a permute for the result vector following the vsumsws instruction.

The correctness of this code is tested by the new sums.c test added in
a previous patch, as well as the modifications to

10 years ago[PPC64LE] Implement little-endian semantics for vec_unpack[hl]

[PPC64LE] Implement little-endian semantics for vec_unpack[hl]

The PowerPC vector-unpack-high and vector-unpack-low instructions
are defined architecturally with a big-endian bias, in that the vector
element numbering is assumed to be "left to right" regardless of
whether the processor is in big-endian or little-endian mode.  This
effectively reverses the meaning of "high" and "low."  Such a
definition is unnatural for little-endian code generation.

To facilitate ease of porting, the vec_unpackh and vec_unpackl
interfaces are designed to use natural element ordering, so that
elements are numbered according to little-endian design principles
when code is generated for a little-endian target.  The desired
semantics can be achieved by using the opposite instruction for
little-endian mode.  That is, when a call to vec_unpackh appears in
the code, a vector-unpack-low is generated, and when a call to
vec_unpackl appears in the code, a vector-unpack-high is generated.

The correctness of this code is tested by the new unpack.c test
added in a previous patch, as well as the modifications to
builtins-ppc-altivec.c in the present patch.

Note that these interfaces were originally incorrectly implemented
when they take a vector pixel argument.  This patch corrects this
implementation for both big- and little-endian code generation.
