new neon functions dont have nacl macros to clear upper 2 bits of address.

neon 32 bit code does not validate with nacl's ncval.  Needs macros for 
loads/stores.

In macro define

#define YUV422TORGB_SETUP_REG                                                  \
    "vld1.8     {d24}, [%[kUVToRB]]            \n"                             \
    "vld1.8     {d25}, [%[kUVToG]]             \n"                             \
    "vld1.16    {d26[], d27[]}, [%[kUVBiasBGR]]! \n"                           \
    "vld1.16    {d8[], d9[]}, [%[kUVBiasBGR]]!   \n"                           \
    "vld1.16    {d28[], d29[]}, [%[kUVBiasBGR]]  \n"                           \
    "vld1.32    {d30[], d31[]}, [%[kYToRgb]]     \n"

there are macros for loads. Does it result in this issue?
