Restructure some of the member-pointer tests, implicitly
removing some that were added without a triple (and moving
their tests into files that appropriately test multiple
architectures).

Get rid of storelv4si builtin as it can be expressed directly.  This is general
goodness because it provides opportunites to cleanup things.  For example,

uint64_t t1(__m128i vA)
{
  uint64_t Alo;
  _mm_storel_epi64((__m128i*)&Alo, vA);
  return Alo;
}

was generating 

	movq	%xmm0, -8(%rbp)
	movq	-8(%rbp), %rax

and now generates

	movd	%xmm0, %rax

In C++11 mode, implement the C++11 semantics for
[basic.lookup.classref]p1 and p4, which concerns name lookup for
nested-name-specifiers and template names, respectively, in a member
access expression. C++98/03 forces us to look both in the scope of the
object and in the current scope, then compare the results. C++11 just
takes the result from the scope of the object, if something is
found. Fixes <rdar://problem/11328502>.

[analyzer] Construct a SymExpr even when the constraint solver cannot
reason about the expression.

This essentially keeps more history about how symbolic values were
constructed. As an optimization, previous to this commit, we only kept
the history if one of the symbols was tainted, but it's valuable keep
the history around for other purposes as well: it allows us to avoid
constructing conjured symbols.

Specifically, we need to identify the value of ptr as
ElementRegion (result of pointer arithmetic) in the following code.
However, before this commit '(2-x)' evaluated to Unknown value, and as
the result, 'p + (2-x)' evaluated to Unknown value as well.

int *p = malloc(sizeof(int));
ptr = p + (2-x);

This change brings 2% slowdown on sqlite. Fixes radar://11329382.
