I've reverted this due to very large compile-time impact, esp. on lencod, see: http://llvm-compile-time-tracker.com/compare.php?from=b1339abb713063363e7804124b8fb3d84143a003&to=de1f5b96adcea52bf7c9670c46123fe1197050d2&stat=instructions:u

For non-LTO cases, me_distortion.c is one of the files with largest impact (~80%).
