AArch64: update vget_set_lane_1.c test output
In the vget_set_lane_1.c test the following entries now generate a zip1 instead of an INS
BUILD_TEST (float32x2_t, float32x2_t, , , f32, 1, 0)
BUILD_TEST (int32x2_t, int32x2_t, , , s32, 1, 0)
BUILD_TEST (uint32x2_t, uint32x2_t, , , u32, 1, 0)
This is because the non-Q variant for indices 0 and 1 are just shuffling values.
There is no perf difference between INS SIMD to SIMD and ZIP on Arm uArches but
preferring the INS alternative has a drawback on all uArches as ZIP being a three
operand instruction can be used to tie the result to the return register whereas
INS would require an fmov.
As such just update the test file for now.
