Log:
Rewrite the shadow-value-cache writeback mechanism so as to be less
obviously stupid. This improves performance of Helgrind by more than
10% on one test.

Split memory_state_machine() into msm_handle_read() and
msm_handle_write(), as it's pointless to keep interpreting "is_w".
This folds out quite a few branches and improves performance of
sequential code frag

Make happens-before caching more 32-bit friendly. Also, make the
table much smaller as that appears to have minimal effect on the hit
