Patch removing the frame pointer from general regs

Here's the patch described; I don't have any sort of extensive framework for
testing the AVR backend - doing such tests would likely be a good idea before
applying this if the general idea is right.

(Patch is git formatted and against 4.5.1 but it should apply to the trunk of
svn fine.)
