-// 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
