ffmpeg | branch: master | Nedeljko Babic <nedeljko.babic at imgtec.com> | Wed Apr 15 15:14:06 2015 +0200| [f4ccf3890285f2c5a055f0cc92405a0f46cdfab2] | committer: Michael Niedermayer

libavutil/softfloat: Change order of fields in SoftFloat structure.

Softfloat will be used in implementation of AAC fixed point decoder.
This change is needed in order to more easily integrate ffmpegs softfloat in
already developed algorithm for AAC.
