Details:
1. Unrolled by a factor 5. This gave around 1GFLOPS gain
2. Changed CMP to subs and remove nan. CMP uses a lot of
compare, which is higher in latency and more number of
instructions. Replacing with subs and remove nan
reduced it to 3 instructions and lighter ones.
3. Added remove nan function.
4. Added AVX512 definition in skx context.
5. Disabled code in AMAXV kernel depending on AVX512 flag
exists or not

For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.
If you don't have time, or are impatient, take a look at the config_registry
file in the top-level directory of the BLIS distribution. It contains a
grammar-like mapping of configuration names, or families, to sub-configurations,
which may be other families. Keep in mind that the / notation:
<config>: <config>/<name>
means that the kernel set associated with <name> should be made available to
the configuration <config> if <config> is targeted at configure-time.
(Some configurations borrow kernels from other configurations, and this is how
we specify that requirement.)
