a0d471e4f8 Attempt to make toHost setiing behave in src_Testbench 
Made the proc start method non-blocking on mmio platform and wired in a new way
to set the tohost addr using a control and status request, and bumpped
WindCoreInterface accordingly

75d1afe8b4 Only push to RAS when the linking instruction is non-speculative. 
That is, don't push in Decode, push from the training structure coming
from Execute, which is delayed until the instruction that issued it is
non-speculative.

01132d165a Enable tracing of physical addresses for RVFI (if PADDR_RVFI is 
defined).
This is done by adding a vector of padder lookup interfaces to the load
store queue.
This should help with targeted memory translation debugging, and also
with compatability with the current Sail RVFI implemenation which is
probably incorrect with respect to the RVFI spec which calls for virtual
addresses in the maddr field.

4e0da006e8 Make non-speculative training optional. 
Removing non-speculative training actually improves performance in
CoreMark.  While it's "safer", I guess this isn't required for BSC.

7b472d4d3c Reduce area overhead by using an unguarded specfifo that does not have 
to be worst-case-sized, but can drop elements if it is full.

08231b7e5c Hopefully don't wedge on ifetch bus error. 
We think that we were wedging on IFetch bus error.
It appears that we didn't make the last instruction fragment valid in the bus error case, and expect that this path was not previously exercised.
This change returns 0s (to hopefully make the error less subtle) in exactly the right number of fragments.
