  -----------
  [ARM] Replace arm_neon_vqadds with sadd_sat

This replaces the A32 NEON vqadds, vqaddu, vqsubs and vqsubu intrinsics
with the target independent sadd_sat, uadd_sat, ssub_sat and usub_sat.
This helps generate vqadds from standard IR nodes, which might be
produced from the vectoriser. The old variants are removed in the
process.
