Bruno Cardoso Lopes 3bde6fe0df Introduce a pass to insert vzeroupper instructions to avoid AVX to 
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper"
llc command line option. This is only the first step (very naive and
conservative one) to sketch out the idea, but proper DFA is coming next
to allow smarter decisions. Comments and ideas now and in further commits
will be very appreciated.
