[PATCH] D33105: [AMDGPU] Turn register pressure estimation into forward tracker

You can do the reset with move - this would not require copy.

If you make advance moving its own iterator then it can skip debugs itself.

Making advance checking end pointer wouldn't increase the number of end checks, as you check it on every iteration of advance loop. You can return bool from advance and break the loop on it. Anyway such checks are cheap.
