	OPNAME is the name of the opcode.
	OPCODE is the 1-byte opcode value.
	OPKIND is the kind of operation.
	OPERAND_TYPE is the type operands affected.
	OPERAND_VALUE tells where to get the value.  (Its meaning
	  depends on OPKIND.) */

/* Various macro used in OPERAND_VALUE:
IMMEDIATE_s1:  An immediate signed 1-byte value in the byte-code stream.
IMMEDIATE_s2:  An immediate signed 2-byte value in the byte-code stream.
IMMEDIATE_u1:  An immediate unsigned 1-byte value in the byte-code stream.
IMMEDIATE_u2:  An immediate unsigned 2-byte value in the byte-code stream.

CONST_INDEX_1:  An immediate unsigned 1-byte index into the constant pool.
CONST_INDEX_2:  An immediate unsigned 2-byte index into the constant pool.

/* More specifically, this is the meaning of the various OPKINDs:

BINOP:	binary operation
	OPERAND_TYPE is the argument type.

UNOP:	unary operation
	OPERAND_TYPE is the argument type.

INVOKE: invoke operations
	OPERAND_VALUE is 1 if interface, 0 otherwise.

OBJECT:	new, checkcast, instanceof

BRANCH: branch operations
	  or VAR_INDEX_2.

STACK:  Various stack operations.

PUSHC:  Push a constant onto the operand stack.
	OPERAND_VALUE maybe be the value to push,
	or IMMEDIATE_s1 or IMMEDIATE_s2 if the constant is immediate,
	or CONST_INDEX_1 or CONST_INDEX_2 for a constant pool index.

LOAD: Push a value from a local variable onto the operand stack.
	OPERAND_VALUE is the index of the local variable in the current
	Java frame.  It can be a literal, or IMMEDIATE_i2.

CONVERT: Convert top of stack value from one type to another.
	OPERAND_TYPE is the argument type.
	OPERAND_VALUE is the result type.

TEST: Compares an integer (popped from the stack) against zero.
	If the test (in OPERAND_VALUE) is true, goto a relative
	offset given by the next two bytes.

COND:  Compares two values (popped from the stack) againt each other.
	If the test (in OPERAND_VALUE) is true, goto a relative
	offset given by the next two bytes.



FIELD: Extracts from or stores into a field.
	OPERAND_TYPE is 1 for a static field, 0 for a regular field.
	OPERAND_VALUE is 1 for a put operation, 0 for a get operation.

	Random bunch of opcodes.
