Subject: Fixes for Kevins O3 model to work with the blocking caches.

src/cpu/o3/fetch_impl.hh:
    Fix ordering so dereference works
src/cpu/o3/lsq_impl.hh:
    Check to make sure we didn't squash already
src/cpu/o3/lsq_unit.hh:
    Fix for counting squashed retrys in the WB count
src/cpu/o3/lsq_unit_impl.hh:
    Make sure to set retryID for stores, and clear it appropriately
