ddf4afaf71 Changes to build with a 512-bit main data bus (with all other busses 
still 64-bits).
Also, the top-level SoC_Top exposes a 64-bit bus still, so hopefully the
GFE configuration is unchanged.
This passes the isa_tests.

066289f8aa Work in progress. 
Wd_Data is moved to 512 bits, and LLC_AXI4_Adapter is updated.
Lots of build errors now; a few have been resolved.

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.
