Bytecode in question

Consider attached testcase.

./opt -std-compile-opts resulted to:

define internal void @__do_global_ctors_aux() {
        br label %cond_true

cond_true:              ; preds = %cond_true, %entry
        br label %cond_true

Probably a constfold issue, fallout from fixing PR166
