Update getCode so it does not make a copy of the array

[rmoreliovlabs]

Description

Removed the call to Arrays.copyOf() method and made getCode() return the array directly. As per @asoto-iov suggestion the getCodeLength() method.

Motivation and Context

Currently the doCODESIZE() and doCODECOPY() methods can, under certain conditions, make a call to the getCode() method that returns a deep copy of the underlying array which can cause perfomance issues if the code array is too big.
