Sam Parker b4a8091a11 [ARM][CostModel] Improve getCastInstrCost 
- Specifically check for sext/zext users which have 'long' form NEON
  instructions.
- Add more entries to the table for sext/zexts so that we can report
  more accurately the number of vmovls required for NEON.
- Pass the instruction to the pass implementation.
