This patch touches some areas that Janne is doing. My thought is to apply this to 4.4.1 to regain some of the 4.3 performance back. I want to wait until branching so I do not interfere with what Janne is doing at the moment which is fairly intrusive and will probably go into 4.5 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38654
