Add sscal.c + microkernels for Haswell, Zen, Skylake and newer.
...
Unlike [dcz]scal, sscal still used the original GotoBLAS SSE code from scal_sse.S.
This code follows dscal as closely as possible, except for the inc_x > 1 code
for which a plain C loop is used much like the one in cscal.c, instead of an
adaptation of the SSE2 asm code of dscal.c (I tried but the performance wasn't
better than the plain C loop).

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

dgemm: Use the skylakex beta function also for haswell

Use sgemm_ncopy_4_skylakex.c also for Haswell
...
sgemm_ncopy_4_skylakex.c uses SSE transpose operations where the
real perf win happens; this also works great for Haswell.
This gives double digit percentage gains on small and skinny matrices

Use the skylake sgemm beta code also for haswell
...
with a few small changes it's possible to use the skylake sgemm code
also for haswell, this gives a modest gain (10% range) for smallish
matrixes but does wonders for very skinny matrixes
