Mixin for CodeGenerator to replace UNPACK_SEQUENCE bytecodes.

The UNPACK_SEQUENCE opcode is not safe because it extracts elements from a sequence without using a safe iterator or making __getitem__ checks.

This code generator replaces use of UNPACK_SEQUENCE with calls to a function that unpacks the sequence, performes the appropriate security checks, and returns a simple list.
