Hello,

this time, +-* for 128 bit integer vectors. I am using an unsigned type sothe compiler knows that we expect wrapping. I don't know why Intel'sdescription of mullo insists that the multiplication is signed, that onlymatters for the high part...


Next parts (waiting for approval for this one) should be:
- same thing with 256 and 512 bit integer vectors
- & | ^ (integer only)

Maybe (or it can wait until the next release):
- < > == abs min max (integer only)
