Address translation request moved from icache to frontend

[yanicasa]

In order to aligned the ways address translation is managed between FETCH and DATA the address translation request is moved from the icache to the frontend.

The change is supposed to be transparent, no functional impact, same perf, same critical path...

@yanicasa @cfuguet I would prefer to move step by step. As the first goal of the PR was to move the address translation request from icache to frontend, can we merge this modification before submitting another PR to improve even more the design ?

[cfuguet]

IMHO, adding a third kill signal to the instruction fetch interface is adding more complexity. And it is kind of still leaving a part of the address translation mechanism in the Icache.
