Avoid using i64 types for vld1q_lane/vst1q_lane intrinsics.
The backend has to legalize i64 types by splitting them into two 32-bit pieces,
which leads to poor quality code. If we produce code for these intrinsics that
uses one-element vector types, which can live in Neon vector registers without
getting split up, then the generated code is much better. Radar 11998303.
