LiveIntervals: Fix handleMove asserting on BUNDLE
The top-level BUNDLE instruction should behave as an ordinary
instruction. It is supposed to have all relevant registers as implicit
operands. Moving it should work as any other instruction. I believe
the assert intended to avoid moving instructions inside bundles.
