This patch addresses a problem encountered by the
ASTImporter when importing the following types:

typedef struct {
} A;

typedef struct {
  A a;
} B;

Suppose we have imported B, but we did not at that
time need to complete it.  Then later we want to
import A.  The struct is anonymous, so the first
thing we want to do is make sure no other anonymous
struct already matches it.  So we set up an
StructuralEquivalenceContext and compare B with A.

This happens at ASTImporter.cpp:2179.

Now, in this scenario, B is not complete.  So we go
and import its fields, including a, which causes A
to be imported.  The ASTImporter doesn’t yet have A
in its list of already-imported things, so we
import A.

After the StructuralEquivalenceContext is finished
determining that A and B are different, the
ASTImporter concludes that A must be imported
because no equivalent exists, so it imports a second
copy of A.  Now we have two different structs
representing A.  This is really bad news.

The patch allows the StructuralEquivalenceContext to
use the original version of B when making its
comparison, obviating the need for an import and
cutting this loop.

Use KEY_WOW64_32KEY when reading the registry in WindowsToolChain.cpp (PR17033)

This exposes a 32-bit view of the registry even when Clang is built as a 64-bit
program. Since Visual Studio is a 32-bit application, this is necessary for us
to find it.

Implement AArch64 vector load/store multiple N-element structure class SIMD(lselem). 
Including following 14 instructions:
4 ld1 insts: load multiple 1-element structure to sequential 1/2/3/4 registers.
ld2/ld3/ld4: load multiple N-element structure to sequential N registers (N=2,3,4).
4 st1 insts: store multiple 1-element structure from sequential 1/2/3/4 registers.
st2/st3/st4: store multiple N-element structure from sequential N registers (N = 2,3,4).

E.g. ld1(3 registers version) will load 32-bit elements {A, B, C, D, E, F} sequentially into the three 64-bit vectors list {BA, DC, FE}.
E.g. ld3 will load 32-bit elements {A, B, C, D, E, F} into the three 64-bit vectors list {DA, EB, FC}.

Locate VS InstallDir in the presence of newer runtime

This fixes getSystemRegistryString() in WindowsToolChain.cpp to
