SAXPY built with OpenXL regresses when compared to SAXPY built with gcc. OpenXL compiler doesn't know that the SAXPY inner kernel assembly is a 64 element loop and to it the remainder loop is the main loop. It vectorizes and interleaves the remainder to be a 48 elements per iteration loop. With a max of 63 iterations, a 48 element loop is mostly not going to get executed, so the 1 element scalar loop that is the remainder after that is probably mostly what gets executed. This can be fixed by adding a pragma, loop interleave_count(2) which will result in 8 element loop. Signed-off-by: Amrita H S <[email protected]>

This reverts commit 9b24b31. It turns out that PRs 4515 and 4520 break the tests under lapack-netlib/TESTING which require SECOND and DSECND. IBM has decided this is a bigger biger problem than the conflict between lapack second_ and the xlf run time.
