amdzen and x86_64 configuration family: On Intel processors supporting
AVX-512, the zen4 sub-configuration was dispatched by default, as even
though it is not optimized specifically for Intel processors, it includes
a range of additional optimizations than are present in the the older skx
sub-configuration. However, the zen4 data path is 256 bit, thus this
sub-configuration uses a mixture of AVX2 and AVX-512 kernels. Now that
zen5 sub-configuration is available, with more extensive use of AVX-512
kernels, switch to use this by default on relevant Intel processors.
intel64 configuration family: On AMD processors supporting AVX-512 or
AVX2, the generic sub-configuation was dispatched by default. Change to
dispatch skx or haswell sub-configuation, based on the available ISA
support.
