Don't perform expensive queries checking for super and sub registers when we know that there aren't any. This speed up LiveVariables on instcombine at -O0 -g from 0.3855s to 0.3503s. Look for more improvements in this area soon! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52804 91177308-0d34-0410-b5e6-96231b3b80d8
