Martin Storsjö f1fd12ef85 lavu/arm: Check for have_vfp_vm instead of !have_vfpv3 for float_dsp_vfp 
This was missed in e754c8e8 / e2710e790c since those functions
weren't exercised by checkasm.

Fixes ticket #6766.

Ben Avison 57641410d1 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%

Ronald S. Bultje 42d3246948 floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.
