cmd/internal/obj/arm64: add ASIMD cross-lane reduction instructions
Add support for ASIMD instructions that reduce a vector to
a scalar by operating across all lanes. These use the ASIMDALL
encoding class from the ARM architecture specification.
Integer cross-lane reductions (.B8, .B16, .H4, .H8, .S4):
Signed max/min across lanes: VSMAXV, VSMINV
Unsigned max/min across lanes: VUMAXV, VUMINV
Floating-point cross-lane reductions (.S4 arrangement):
FP max/min across lanes: VFMAXV, VFMINV
FP max/min across lanes (NM): VFMAXNMV, VFMINNMV
