In 4.4, gcc does alignment (output array) based versioning -- Sri's
patch has the effect of doing the samething but only for selected

On core2, unaligned vector load/store using movdqu is a very slow operation.
Experiments show it is six times slower than movdqa (aligned) and this is
irrespective of whether the resulting data happens to be aligned or not.
For Corei7, there is no performance difference between the two and on

This patch adds a new flag to mark sections as exclude sections. Such
sections will be discarded by the linker. Also, mark .gnu.callgraph
sections which store the callgraph edge profile info as exclude
sections.
