Things of note in this edition:
* Incorprorated Bernd Schmidt's suggestions for treatment of benefit
in and around general_induction_var.
* Fixed a long-standing bug in express_from that caused the ia32
code-gen lossage.
* Fixed a bit in find_mem_givs that was causing -frerun-loop-opt to
generate worse code on Alpha. I am now interested to see code
samples that generate different code when loop is rerun.
