a17edac875 flash: Fix barrier stall with DEBUG
Verified for up to P_expected on 2nd iter; O_before_PV is partially
correct

b652e25945 flash: Warp-specialize between warp 0 and 1-7
Finishes without stalls; No dependency check between O rescale and
GEMM-II.

714b9f501e flash: Restructure to do delayed fence for better concurrency
Verified up to O_before_PV of 2nd iteration; O_after_PV needs preload
fix.
FIXME: Stalls at barrier without DEBUG set.
