[ibm-gcc-4_3-patch] Backport power7 changes to ibm-gcc-4_3-patches

[Michael Meissner <meissner at linux dot vnet dot ibm dot com>]

I sent this out previously, but evidently the patches were too large, so I'm
bzipping the patches.  These two patches backported most of the power7
development branch to the ibm-gcc-4_3-branch.
