Subject: Also use shrinkToUses after AdjustCopiesBackFrom().
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c6b9ebdd6400c5ade1b5b211252cd251b6ef07ae;p=oota-llvm.git

Also use shrinkToUses after AdjustCopiesBackFrom().

The 'last use' may not be in the same basic block, and we still want a correct
live range.
