This turned up as part of rust-lang#3170. When constructing an `undef` value to return in the error case, we were trying to get the element type of the Rust-level value being indexed instead of the underlying array; when indexing a slice, that's not an array and the LLVM assertion failure reflects this. The regression test is a lightly altered copy of `const-array-oob.rs`.
