4d2f62150d aarch64/opusdsp: implement NEON accelerated postfilter and deemphasis
153372 UNITS in postfilter_c,   65536 runs,      0 skips
73164 UNITS in postfilter_neon,   65536 runs,      0 skips -> 2.1x speedup

80591 UNITS in deemphasis_c,  131072 runs,      0 skips
43969 UNITS in deemphasis_neon,  131072 runs,      0 skips -> 1.83x speedup

Total decoder speedup: ~15% on a Raspberry Pi 3 (from 28.1x to 33.5x realtime)

Deemphasis SIMD based on the following unrolling:
const float c1 = CELT_EMPH_COEFF, c2 = c1*c1, c3 = c2*c1, c4 = c3*c1;
float state = coeff;

for (int i = 0; i < len; i += 4) {
    y[0] = x[0] + c1*state;
    y[1] = x[1] + c2*state + c1*x[0];
    y[2] = x[2] + c3*state + c1*x[1] + c2*x[0];
    y[3] = x[3] + c4*state + c1*x[2] + c2*x[1] + c3*x[0];

    state = y[3];
    y += 4;
    x += 4;
}

Unlike the x86 version, duplication is used instead of pslldq so
the structure and tables are different.

c8bc9d1380 aarch64: vp8: Move the vp8dsp makefile entries to the right places
Even if NEON would be disabled, the init functions should be built
as they are called as long as ARCH_AARCH64 is set.

These functions are part of a generic DSP subsytem, not tied directly
to one decoder. (They should be built if the vp7 decoder is enabled,
even if the vp8 decoder is disabled.)

c950beb68d aarch64: vp8: Fix assembling with clang
This also partially fixes assembling with MS armasm64 (via
gas-preprocessor).

The movrel macro invocations need to pass the offset via a separate
parameter. Mach-o and COFF relocations don't allow a negative
offset to a symbol, which is handled properly if the offset is passed
via the parameter. If no offset parameter is given, the macro
evaluates to something like "adrp x17, subpel_filters-16+(0)", which
older clang versions also fail to parse (the older clang versions
only support one single offset term, although it can be a parenthesis.

7e42d5f0ab aarch64: vp8: Optimize vp8_idct_add_neon for aarch64
The previous version was a pretty exact translation of the arm
version. This version does do some unnecessary arithemetic (it does
more operations on vectors that are only half filled; it does 4
uaddw and 4 sqxtun instead of 2 of each), but it reduces the overhead
of packing data together (which could be done for free in the arm
version).

This gives a decent speedup on Cortex A53, a minor speedup on
A72 and a very minor slowdown on Cortex A73.

Before:        Cortex A53    A72    A73
vp8_idct_add_neon:   79.7   67.5   65.0
After:
vp8_idct_add_neon:   67.7   64.8   66.7

49f9c4272c aarch64: vp8: Skip saturating in shrn in ff_vp8_idct_add_neon
The original arm version didn't do saturation here. This probably
doesn't make any difference for performance, but reduces the
differences.

85bfaa4949 aarch64: vp8: Use the proper aarch64 form for conditional branches
The previous form also does seem to assemble on current tools,
but I think it might fail on some older aarch64 tools.

26d7af4c38 aarch64: vp8: Fix assembling with clang
This also partially fixes assembling with MS armasm64 (via
gas-preprocessor).

The movrel macro invocations need to pass the offset via a separate
parameter. Mach-o and COFF relocations don't allow a negative
offset to a symbol, which is handled properly if the offset is passed
via the parameter. If no offset parameter is given, the macro
evaluates to something like "adrp x17, subpel_filters-16+(0)", which
older clang versions also fail to parse (the older clang versions
only support one single offset term, although it can be a parenthesis.
