	Informs the replacement policy that an access has occurred.

void	eviction_update (int set_idx, int way) override
	Informs the replacement policy that an eviction has occurred.

Detailed Description

A replacement policy that uses a bit per way to track access frequency.

On access, a way's bit is set to 1. Once all bits are set, the whole set's bits are set to 0. A random way with a 0 bit is chosen for replacement.
