When materializing constant i1 values, they must be zero extended. We represent i1 values as [0, 1], not [0, -1], in i32 registers. As it turns out, this code path was dead for i1 values prior to r216006 (which is why this did not manifest in miscompiles until recently). Fixes -O0 self-hosting on PPC64/Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224842 91177308-0d34-0410-b5e6-96231b3b80d8
