This isn't normally a problem, however, it can lead to problems when switching between CPU models. If switching from a real CPU in the middle of an fprem loop to a simulated CPU, the output of the fprem loop becomes correupted. This changeset changes the fprem implementation to work like the one on real hardware. |

A common pattern is a switch statement that check for the size of a packet and then calls the corresponding Packet::(get|set)<uintXX_t> methods. Simplify this by implementing Packet::(get|set)UintX helper functions. The getter reads a word of the size specified in the packet and the specified endianness. The word is then zero-extended to 64 bits. Conversely, the setter truncates the word down to the size required in the packet and then byte-swaps it to the desired endianness.
