[AArch64][SVE] Add missing movprfx attribute to some ternary arithmetic patterns
The two affected SVE2 patterns in this patch output a movprfx'ed instruction in their second alternative
but don't set the "movprfx" attribute, which will result in the wrong instruction length being assumed by the midend.
This patch fixes that in the same way as the other SVE patterns in the backend.
Bootstrapped and tested on aarch64-none-linux-gnu.

* config/aarch64/aarch64-sve2.md (@aarch64_sve_<sve_int_op><mode>:
Specify movprfx attribute.
(@aarch64_sve_<sve_int_op>_lane_<mode>): Likewise.
