Matthias Braun 3865b1d35b LiveIntervalAnalysis: Fix handleMoveDown() problem ...

If we move a last-use register read to a later position we may skip
intermediate segments. This may require us to not only extend the
segment before the NewIdx, but also extend the segment live-in to
OldIdx.

This switches LiveIntervalTest to use AMDGPU so we can test subregister
liveness.
