Nice work! This allows building with LTO on gcc-4.9. gcc-5.3.0 however fails to
build it, throwing a bunch of these around:

/usr/include/bits/string3.h:50:1: error: inlining failed in call to
always_inline ‘memcpy’: target specific option mismatch


Also, unlike your P4, I cannot detect any measurable performance improvements
(Intel Sandy Bridge). Unfortunate.

All tests done with xf86-video-intel from today's git.
