+Operation: OP_CISINST
+
+       Implements the CEE_MONO_CISINST opcode that is decoded from
+       the CIL stream.
+
+       This opcode takes as input an object reference and a class,
+       and leaves on the assigned register:
+
+               0. if the object is an instance of the class,
+               1. if the object is not instance of the class,
+               2. if the object is a proxy whose type cannot be determined.

+
+       Implements the CEE_MONO_CCASTCLASS opcode that is decoded from
+       the CIL stream.
+
+       This opcode takes as input an object reference and a class,
+       and leaves on the assigned register:
+
+               0. if the object is an instance of the class,
+               1. if the object is a proxy whose type cannot be determined
