extremity
negation

003 : modify DIFFERENCE macro to reduce line duplication
004 : add SIMD for grainextract, grainmerge, average, extremity, negation
005 : add checkasm test for grainextract, grainmerge, average, extremity,
negation



Checkasm result :
grainextract_16_c: 11639.2
grainextract_16_sse4: 1047.2
grainextract_16_avx2: 546.4

grainmerge_16_c: 11719.9
grainmerge_16_sse4: 1045.7
grainmerge_16_avx2: 548.7
