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!

f8ad5344c2 Fix casum fallback kernel.
This kernel is only used on Skylake+ if the kernel with AVX512
intrinsics can't be used, but used the variable x1 incorrectly
in the tail end of the loop, as it is still at the initial
value instead of where x points to.

This caused 55 "other error"s in the LAPACK tests
(https://github.com/OpenMathLib/OpenBLAS/issues/4282)

This change makes casum.c as similar as possible as zasum.c,
because zasum.c does this correctly.

394a1fd1bf LoongArch64: Compatible with early internal toolchain
__loongarch_grlen and __loongarch_frlen were introduced in gcc version 8.3.0
(Loongnix 8.3.0-6.lnd.vec.31) internally within Loongson to standardize the
general and floating-point register widths. However, previous versions did
not have them, requiring additional checks to be added.
