Include the use kind along with the expression in the key of the
use sharing map. The reconcileNewOffset logic already forces a separate use if the kinds differ, so incorporating the kind in the key means we can track more sharing opportunities. More sharing means fewer total uses to track, which means smaller problem sizes, which means the conservative throttles don't kick in as often. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106396 91177308-0d34-0410-b5e6-96231b3b80d8
