Due diligence tweaks.
format change
cleaned mask & int32, only test141 fails
cleaned int64 added fails info
cleaned float added fails info
complete cleaning
workong on shuffle/rotate for double, there seems to be a bug in cvt2zmm cvt2hilo
knc-i1x16.h is cleaned: int32,float,double are complete, int64 is partially complete
fixed lshr/ashr/shl shifts. __mul i64 vector version for icc < 14.0.0 works only on signed, so  commented it out in favour of sequential
fixed zmm __mul for i64 with icc < 14.0.0, 4 knc::fails lefts, but I doubt these are due to this include..
