+// 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
