where are you getting "sse4_2 capable machines which is a majority" ?  iiuc, 
AMD doesn't include SSE4.2 support.  Intel released it in their CPU's starting 
in 2007 w/Nehalem, and i don't believe it's in any of their Atom CPUs.

so can you requalify your justification for removal of these funcs to cover 
the significant install base that lacks SSE4.2 ?
