f3329c419b RegisterPressureTracker: fix findUseBetween to handle DebugValue 
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169427 91177308-0d34-0410-b5e6-96231b3b80d8

9493dae613 Use the 'count' attribute to calculate the upper bound of an array. 
The count attribute is more accurate with regards to the size of an array. It
also obviates the upper bound attribute in the subrange. We can also better
handle an unbound array by setting the count to -1 instead of the lower bound to
1 and upper bound to 0.
