Patch for bundled instructions in LiveIntervalsAnalysis

[Stephen Rogers via llvm-commits]

Hi all,

Attached is a patch I have made to the function "LiveIntervals::handleMove"
in "lib/CodeGen/LiveIntervalAnalysis.cpp". I have changed the assertion on "
!MI.isBundled()" to "!MI->isInsideBundle()" since it is possible (and
necessary) to handle the move of a bundle header instruction. This is
necessary for updating the live intervals of bundled instructions.

Thanks,
Stephen
