2008f76054 dca: remove unused decode_hf function and quant_d tables 
They were superseded with their integer equivalents. Rename integer
decode_hf to decode_hf.

705f5e5e15 arm64: port synth_filter_float_neon from arm 
~25% faster dts decoding overall. The checkasm CPU cycles numbers are
not that useful since synth_filter_float() calls FFTContext.imdct_half().

synth_filter_float_c:    1866.2       3490.9
synth_filter_float_neon:  915.0       1531.5

With fftc.imdct_half forced to imdct_half_neon:
