Nemanja Ivanovic 3d641da82e [PowerPC] Improvements for BUILD_VECTOR Vol. 4
This is the final patch in the series of patches that improves
BUILD_VECTOR handling on PowerPC. This adds a few peephole optimizations
to remove redundant instructions. It also adds a large test case which
encompasses a large set of code patterns that build vectors - this test
case was the motivator for this series of patches.
