makes explicit use of Intel intrinsics to powerp64/powerpc64le.

|
|
It is the user's responsibility to determine if the results are
|
|
acceptable and make additional changes as necessary.
|
|
|

Note that much code that uses Intel intrinsics can be rewritten in

|
standard C or GNU C extensions, which are more portable and better

optimized across multiple targets. */
