SBR DSP x86: implement SSE sbr_sum_square_sse
...
The 32bits targets have been compiled with -mfpmath=sse for proper reference.
sbr_sum_square C /32bits: 82c (unrolled)/102c
C /64bits: 69c (unrolled)/82c
SSE/32bits: 42c
SSE/64bits: 31c
Use of SSE4.1 dpps to perform the final sum is slower.
Not unrolling to perform 8 operations in a loop yields 10 more cycles.

aacsbr: move some simdable loops to function pointers
...
This prepares for assembly optimisations by moving the most
time-consuming loops to functions called through pointers
in a new context.
