armv6: Accelerate butterflies_float
I benchmarked the result by measuring the number of gperftools samples that hit anywhere in the AAC decoder (starting from aac_decode_frame()) or specifically in butterflies_float_c() / ff_butterflies_float_vfp() for the same sample AAC stream: Before After Mean StdDev Mean StdDev Confidence Change Audio decode 1542.8 43.7 1470.5 41.5 100.0% +4.9% butterflies_float 130.0 11.9 70.2 12.1 100.0% +85.2% Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
