+//
+// Representation of the sequence of machine instructions created
+// 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
