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.)

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.

If we fill with black then the generated palette will have one color more
than what the user requested. This also resulted in unwanted black specks in
the output of paletteuse, especially when generating small palettes.

- Clamp ME range to -64..63 (prevents corruption when me_range is too high)
- Allow MV's up to *and including* the positive range limit
- Allow out-of-edge ME by padding the prev buffer with a border of 0's
- Try previous MV before checking the rest (improves speed in some cases)
- More robust logic in code - ensure *mx,*my,*xored are updated together

- Improve block choices by counting 0-bytes in the entropy score
- Make histogram use uint16_t type, to allow byte counts from 16*16
(current block size) up to 255*255 (maximum allowed 8bpp block size)
- Make sure score table is big enough for a full block's worth of bytes
- Calculate *xored without using code in inner loop

Optimize theora decoding with mmi in functions:
1. ff_vp3_idct_add_mmi
2. ff_vp3_idct_put_mmi
3. ff_vp3_idct_dc_add_mmi
4. ff_put_no_rnd_pixels_l2_mmi

Theora decoding speed improved about 32%(from 88fps to 116fps, Tested on loongson 3A3000).
