There is nothing stopping us from writing a boost library that does just that, implementing it as portable C++ that is slow and providing inline assmeber (or intrinsics based) implementations for common platforms.  Then we can make a proposal to add these to the std library.

Anyone want to suggest it as a GSOC project they are willing to mentor?  I can't mentor more than one project, unfortunately.
