[PATCH] D74619: [ARM] Enabling range checks on Neon intrinsics' lane arguments

Hi @leonardchan ,

I've double-checked the Neon intrinsics reference and it indeed confirms that the only allowed value for the lane argument for `vdupq_lane_f64` is `0`:

  Argument Preparation
  
  vec → Vn.1D 
  0 << lane << 0

(https://developer.arm.com/architectures/instruction-sets/simd-isas/neon/intrinsics?search=vdupq_lane_f64)

I believe the observed behaviour is expected.
