795285c587 Fix thinko in skylake beta handling 
casting ints is cheaper but it has a rounding, not memory casing effect, resulting in
invalid outcome

d321448a63 dgemm: use dgemm_ncopy_8_skylakex.c also for Haswell 
The dgemm_ncopy_8_skylakex.c code is not avx512 specific and gives
a nice performance boost for medium sized matrices
