// *********************************** NOTE ***********************************
// ** For POWER8 Little Endian, the VSX swap optimization relies on knowing  **
// ** which VMX and VSX instructions are lane-sensitive and which are not.   **
// ** A lane-sensitive instruction relies, implicitly or explicitly, on      **
// ** whether lanes are numbered from left to right.  An instruction like    **
// ** VADDFP is not lane-sensitive, because each lane of the result vector   **
// ** relies only on the corresponding lane of the source vectors.  However, **
// ** an instruction like VMULESB is lane-sensitive, because "even" and      **
// ** "odd" lanes are different for big-endian and little-endian numbering.  **
// **                                                                        **
// ** When adding new VMX and VSX instructions, please consider whether they **
// ** are lane-sensitive.  If so, they must be added to a switch statement   **
// ** in PPCVSXSwapRemoval::gatherVectorInstructions().                      **

//        2. Employ a more disciplined use of AddedComplexity, which would provide
//           more fine-grained control than option 1. This would be beneficial
//           if we find situations where Altivec is really preferred over VSX.
