Log:
Add support for speculative loads

[Branch only patch -- not intended for trunk in its current state]

This patch adds support for speculative loads in cases where the loads
are (or can be made to be) aligned to a full vector size.  Such loads
can never partially fault and they should be more efficient than
first-faulting loads for the cases that they can handle.
