see this message (and the one before it).

must work through to see if there is a way to combine the Mem Hazard Matrix logic with addr match and spot interleaved LDs and STs that do not clash.

at the moment, *any* LD will stop future STs from going through.  *any* ST likewise stops LDs from going through.

it *may* be possible to use addr match on LSBs to determine which interleaved LDs and STs can be separated into batches of LDs and batches of STs.
