f5bd639863 Don't write badaddr on misaligned fetch exceptions 
It's optional, and we were doing it wrong before, so just don't do it.

dbf599f6a1 Support SynchronizerShiftReg(sync = 0)

might not always be needed.

d93d7b9fa4 Only merge stores that aren't yet pending 
This fixes a deadlock (and possibly memory corruption, though that is
unconfirmed).  The following sequence manifests it, assuming t0
is 32-byte aligned:

    sw t0, 0(t0)
    sw t0, 16(t0)
    lw t1, 4(t0)
    lw t2, 4(t0)

1f606d924f Don't perform in-place correction if there was a recent store (#988) 
Since the correction updates the entire word, the WAW hazard detection
logic is not sufficient to prevent overwriting a recent store.  So,
re-read the word after all pending stores have drained.
