Inline function called from test/dct16x16_test.cc wouldn't build due to:
invalid operands of types ‘__gnu_cxx::__enable_if<true, double>::__type
{aka double}’ and ‘int’ to binary ‘operator>>’
return (abs(ref->row) >> 3) < COMPANDED_MVREF_THRESH &&
this converts the test to abs() < COMPANDED_MVREF_THRESH << 3 which
hides the promotion issue.

Keep vp8 sixtap read within bounds
When filtering it needs 6 pixels: 2 prior to the source, the source, and
3 after the source.
When filtering 16 wide, that means 21. To accomplish this the SSE2 reads
[-2] to [5], [6] to [13], and [14] to [21], a total of 24 bytes (reading
in groups of 8 is easy)
The filter then shifts this last set to the top half of the register and
uses 'or' to combine it with the previous set.
Valgrind detected an issue reading pixels [19], [20] and [21]:
Address 0x7f581c2 is 434 bytes inside a block of size 441 alloc'd
Note: we only need pixels [16], [17], and [18] as context for [15].
To fix this, it now reads 8 bytes starting at [11], which re-loads [11]
through [13], but stops at [18] and does not over-read any values.
This is shifted by 5 and 'or'd with xmm1. Although the lower bits are
not cleared, they overlap directly with [11] through [13], so 'or'
produces the correct results.

Enable ssse3 bilinear tests
The code only has issues when xoffset == 0 and yoffset == 0 which
represents a simple copy. Presumably this case does not need to be
handled because the issue has existed since 2010.

Restore vp8_bilinear_predict4x4_neon
This function was removed when clang started introducing alignment hints
which caused the 32 bit vld1_lane_u32/vst1_lane_u32 to fail:
https://llvm.org/bugs/show_bug.cgi?id=24421
The load has been rendered safe with an implementation ~indiscernible
performance-wise that uses _u8 and over-reads just a touch.
It is still ~5x faster than C in the unaligned case and doing both
filters.

The load has been rendered safe with an implementation ~indiscernible

The store, when unaligned, has a version that is ~25% slower but safe
when xoffset = 0 (second pass filter only). When the first pass filter
(or both) are in play, the new version is almost identical in speed.
Worst case performance (both filters, unaligned stores) is roughly 3-4x
faster than C.

In regards to the safety of these casts they are of two types:-
- Normalized bits per (16x16) MB stored in a 32 bit int (This is safe as bits
per MB even with << 9 normalization cant overflow 32 bits. Even raw 12
bits hdr source even would only be 29 bits :- (4+4+12+9) and the encoder
imposes much stricter limits than this on max bit rate.
- Cast as part of variance calculations. There is an internal cast up to 64 bit
for the Sum X Sum calculation, but after normalization dividing by the number
of points the result will always be <= the SSE value.

Modified resize loop constraints.
Using a tighter resize constraint on undershoot seems to help
results (especially SSIM) as significant undershoot on a frame
seems to have more of a damaging impact than overshoot.
This patch has been tuned so that in local testing using the
derf set it is encode speed neutral for speed setting 2.
Average quality result for speed 2 (psnr,ssim) were as follows:-
