It's currently possible to `load <32 x i1>`, freeze the result, and bitcast it to i32. But the backend is likely to turn that into something messy. Otherwise, no, there isn't really any way to load a partially poisoned value as an i32. This is loosely related to https://discourse.llvm.org/t/a-memory-model-for-llvm-ir-supporting-limited-type-punning/61948 .
