[PATCH] Debug info: Cleanup collectChangingRegs

[Frédéric Riss]

Noticed while working on DbgValueHistoryCalculator.cpp.

    Cleanup collectChangingRegs
    
    The handling of the epilogue is best expressed as an early exit and
    there is no reason to look for register defs in DbgValue MIs.

OK to apply?
