Pass around i1 as is instead of going through u8

-                    let v = base::from_immediate(&bx, v);
+                    if common::val_ty(v) == Type::i1(bx.cx) {
+                        v = bx.zext(v, Type::i8(bx.cx))
+                    }


Am not sure about this, but I feel like boolean arrays should also use memset when they can, right?

I can't reproduce that locally, I wonder if this is an intermittent, or a failure specific to using LLVM 3.9.

nox · 2018-05-02T13:27:31Z

Seems like this was indeed an intermittent.

Hmm, looking at this again, the special-case for bool could go better in scalar_llvm_type_at, which would let you remove this whole comment too.
