aarch64: vp9: Implement NEON loop filters

This work is sponsored by, and copyright, Google.

These are ported from the ARM version; thanks to the larger
amount of registers available, we can do the loop filters with
16 pixels at a time. The implementation is fully templated, with
a single macro which can generate versions for both 8 and
16 pixels wide, for both 4, 8 and 16 pixels loop filters
(and the 4/8 mixed versions as well).

For the 8 pixel wide versions, it is pretty close in speed (the
v_4_8 and v_8_8 filters are the best examples of this; the h_4_8
and h_8_8 filters seem to get some gain in the load/transpose/store
part). For the 16 pixels wide ones, we get a speedup of around
1.2-1.4x compared to the 32 bit version.

Examples of runtimes vs the 32 bit version, on a Cortex A53:
                                       ARM AArch64
vp9_loop_filter_h_4_8_neon:          144.0   127.2

vp9_loop_filter_v_16_16_neon:        546.0   453.7

The speedup vs C code in checkasm tests is around 2-7x, which is
pretty much the same as for the 32 bit version. Even if these functions
are faster than their 32 bit equivalent, the C version that we compare
to also became around 1.3-1.7x faster than the C version in 32 bit.

Based on START_TIMER/STOP_TIMER wrapping around a few individual
functions, the speedup vs C code is around 4-5x.

Examples of runtimes vs C on a Cortex A57 (for a slightly older version
of the patch):

transforms in slices 8 pixels wide instead of 4. This gives
a speedup of around 1.4x compared to the 32 bit version.

The fact that aarch64 doesn't have the same d/q register
aliasing makes some of the macros quite a bit simpler as well.

Examples of runtimes vs the 32 bit version, on a Cortex A53:
                                       ARM  AArch64

vp9_inv_wht_wht_4x4_add_neon:         63.0     57.7

The speedup vs C code (2-4x) is smaller than in the 32 bit case,
mostly because the C code ends up significantly faster (around
1.6x faster, with GCC 5.4) when built for aarch64.

Examples of runtimes vs C on a Cortex A57 (for a slightly older version

The speedup vs C code is around 2-6x. The numbers are quite
inconclusive though, since the checkasm test runs multiple filterings
on top of each other, so later rounds might end up with different
codepaths (different decisions on which filter to apply, based
on input pixel differences). Disabling the early-exit in the asm
doesn't give a fair comparison either though, since the C code
only does the necessary calcuations for each row.

Based on START_TIMER/STOP_TIMER wrapping around a few individual
functions, the speedup vs C code is around 4-9x.

This is pretty similar in runtime to the corresponding routines
in libvpx. (This is comparing vpx_lpf_vertical_16_neon,
vpx_lpf_horizontal_edge_8_neon and vpx_lpf_horizontal_edge_16_neon
to vp9_loop_filter_h_16_8_neon, vp9_loop_filter_v_16_8_neon
and vp9_loop_filter_v_16_16_neon - note that the naming of horizonal
and vertical is flipped between the libraries.)

In order to have stable, comparable numbers, the early exits in both
asm versions were disabled, forcing the full filtering codepath.

arm: vp9: Add NEON itxfm routines

This work is sponsored by, and copyright, Google.

For the transforms up to 8x8, we can fit all the data (including
temporaries) in registers and just do a straightforward transform
of all the data. For 16x16, we do a transform of 4x16 pixels in
4 slices, using a temporary buffer. For 32x32, we transform 4x32
pixels at a time, in two steps of 4x16 pixels each.

Examples of relative speedup compared to the C version, from checkasm:
                         Cortex       A7     A8     A9    A53
vp9_inv_adst_adst_4x4_add_neon:     3.39   5.83   4.17   4.01
vp9_inv_adst_adst_8x8_add_neon:     3.79   4.86   4.23   3.98

vp9_inv_dct_dct_16x16_add_neon:     3.35   3.44   3.36   3.79

vp9_inv_wht_wht_4x4_add_neon:       3.22   5.13   3.53   3.77

Thus, the speedup vs C code is around 3-6x.

This is mostly marginally faster than the corresponding routines
in libvpx on most cores, tested with their 32x32 idct (compared to
vpx_idct32x32_1024_add_neon). These numbers are slightly in libvpx's
favour since their version doesn't clear the input buffer like ours
do (although the effect of that on the total runtime probably is
negligible.)

                           Cortex       A7       A8       A9      A53
vp9_inv_dct_dct_32x32_add_neon:    18436.8  16874.1  14235.1  11988.9
libvpx vpx_idct32x32_1024_add_neon 20789.0  13344.3  15049.9  13030.5

Only on the Cortex A8, the libvpx function is faster. On the other cores,
ours is slightly faster even though ours has got source block clearing
integrated.

isn't very register starved to begin with, so there's not much
to be gained from having more spare registers here - we only
avoid having to clobber callee-saved registers.

For encoding, this allocator gets invoked not only for the pool of input
