While processing scalar IR nodes corresponding to Java SE APIs [Short/Character/Integer/Long].reverseBytes SLP analysis checks passes since relevant support already existed. This bug fix patch handles missing scalar reversebyte opcode checks in SLP backed to enable creation of corresponding vector IR nodes.
