ecae1389df Reduce duplication in kernel definitions 
These files are exactly the same, so I believe we can reduce these files
down. Other files require a slightly more complex unpicking.

7a4fef4f60 Tweak SVE dot kernel 
This changes the SVE dot kernel to only predicate when necessary as well
as streamlining the assembly a bit. The benchmarks seem to indicate this
can improve performance by ~33%.

c34e2cf380 Use _mm_set1_epi{32,64x} to init mask in x86-64 [cz]asum 
for skylake kernels. This is the same method as used in [sd]asum.
_mm_set1_epi64x was commented out for zasum, but has the advantage
of avoiding possible undefined behaviour (using an uninitialized
variable), optimized out by NVHPC and icx. The new code works
fine with those compilers.

For GCC 12.3 the generated code is identical; no matter what method
you use, the compiler optimizes the code into a compile-time
constant, there is no performance benefit using mm_cmpeq_epi8
since the corresponding instruction (VPCMPEQB) isn't actually
generated!
