Link Time Optimization patchkit v3

LTO allows the compiler to do global optimization over the whole kernel.

Updated version of the LTO patchkit, mainly for fixing Sam's review
comments. I also rebased to 3.14-rc3 and added a fix for bloat-o-meter
with gcc 4.9

See the individual patches for a detailed description

Dependencies: asmlinkage patchkit (posted two weeks ago), kallsyms patchkit
(plus LTO capable toolchain, see documentation)
