[LLVMdev] MergeInClobberRanges

Why does LiveInterval::MergeInClobberRanges set the definition index
as unknown?  Why would the definition index not be the definition index
for the range merged in from the other interval?  I suppose if two ranges
overlap it's not clear what to set the def index to.  Perhaps it should result
in two separate ranges with different def indices.
