Changed name of LSU's FetchCount to WordCount. This better reflex the dual usage as fetch and eviction counters.
...
Fixed bug with the uncached memory operations. The periph tests still do not pass. They enter into what seems an intentional infinite loop. Then a uart interrupt jumps into an ISR but the ISR returns back to the loop.

Removed the fault state from the hptw. Now writing TLB faults into the I/DTLBs. This has two advantages.
...
1: It simplifies the interactions between the caches and the hptw.
2: instruction page faults are fetched 3 times, caching them in the ITLB speeds up this process.
There are two downsides.
1: Pollute the TLBs with not very relavent translations
2: Have to compute the misalignment. This can be cached in the TLB which only costs 1 flip flop
for each TLB line.
