sbrdsp: Unroll and use integer operations
This patch can be controversial, by assuming floats are IEEE-754 and particular behaviour of the FPU will get in the way. Timing on Arrandale and Win32 (thus, x87 FPU is used in the reference). sbr_qmf_pre_shuffle_c: 115 to 76 sbr_neg_odd_64_c: 84 to 55 sbr_qmf_post_shuffle_c: 112 to 83 Signed-off-by: Diego Biurrun <diego@biurrun.de>
