+//   for a single VM instruction.  Additionally records information
+//   about hidden and implicit values used by the machine instructions:
+//   about hidden values used by the machine instructions:
+// 
+//   "Temporary values" are intermediate values used in the machine
+//   instruction sequence, but not in the VM instruction
+//   Note that such values should be treated as pure SSA values with
+//   no interpretation of their operands (i.e., as a TmpInstruction
+//   object which actually represents such a value).
+// 
+//   (2) "Implicit uses" are values used in the VM instruction but not in
+//       the machine instruction sequence
