returned by getShiftAmountTy may be too small to hold shift values (it is an i8 on x86-32). Before and during type legalization, use a large but legal type for shift amounts: getPointerTy; afterwards use getShiftAmountTy, fixing up any shift amounts with a big type during operation legalization. Thanks to Dan for writing the original patch (which I shamelessly pillaged). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63482 91177308-0d34-0410-b5e6-96231b3b80d8
