Memory Leaks while handling Realloc Calls

The shadow memory design in BBOps.cc should be reconsidered. Currently, shadow memory is allocated as a contiguous byte array with each new memory allocation requesting memory at the end of the array. On realloc instructions, a new (larger) memory is allocated at the rear of the array while the old allocation cannot be freed.

Future Work: Consider implementing shadow memory as an array/map of pointers to memory allocations.
