Add SMLSL, SQRSHRN and SRSHR (Vector) cpu instructions, nits (#225)
* Add SMLSL, SQRSHRN and SRSHR (Vector) cpu instructions

* Address PR feedback

* Address PR feedback

* Remove another useless temp var

* nit: Alignment

* Replace Context.CurrOp.GetBitsCount() with Op.GetBitsCount()

* Fix encodings and move flag bit test out of the loop
