Bootstrapped and regression tested on powerpc64-linux-gnu.  Verified no
performance degradations on that target for SPEC CPU2000 and CPU2006.

I'm looking for eventual approval for trunk after any comments are
resolved.  Thanks!

How do the costs look like for the two transforms you mention in the head comment of locally_poor_mem_replacement?
