Fix a regression in my isIntegral patch that broke 471.omnetpp. This is
because TargetData::getTypeSize() returns the same for i1 and i8. This fix is not right for the full generality of bitwise types, but it fixes the regression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33237 91177308-0d34-0410-b5e6-96231b3b80d8
