4bd87a9b9e vp8_subpixelvariance_neon: right size coeff table
only uint8 is required; each use only loads one value as a uint8
quiets a few type conversion warnings

fd3658b0e4 replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNED
this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

eabb793f3b Use correct buffer size in vp8 subpixel variance
In vp8_sub_pixel_variance8x8_neon the temp2 buffer is only initialized
to kHeight8 * kWidth8. However, in the case that xoffset != 0 and
yoffset == 0, var_filter_block2d_bil_w8 is called with output_width
kHeight8PlusOne.

Thanks to cmugurel for diagnosing and yulius for the patch.

0002da32e6 arm: Fix building vp8_subpixelvariance_neon.c with MSVC
Use the right return values - vget_low_s64 returns int64x1_t, not
a normal int64_t.

Also make __builtin_prefetch a no-op on MSVC for this file.
