Joe Ramsay 5b82fb1882 AArch64: Optimise SVE scalar callbacks 
Instead of using SVE instructions to marshall special results into the
correct lane, just write the entire vector (and the predicate) to
memory, then use cheaper scalar operations.

Geomean speedup of 16% in special intervals on Neoverse with GCC 14.
