Title: Performance improvement on convolution using SSE

It's a really tiny change.
I saw that the add function in THVector.h using SSE on float and double wasn't unrolled like the others function. Non unrolling prevents to optimize correctly the SSE instruction pipeline.
This modification leads to increase speed by 28% on float and double convolution.
