took laptop timings
./bm_kiss_float -x 10000 -n 2048

to 1.57

made some things const -- doesn't really have an effect under gcc, but it might under some compilers
added asm target to check to see if the assembly code changes

split kiss_fft.c into multiple files. It seems the best approach, all things considered.
