<pre>The input IR is invalid. The size of the alloca must match the size described
by debug info. I'm in the process of adding an assert to the verifier to
complain about this directly. There is some question of whether we can encode
the fact that even though something is stored as i8, it's actually only one bit
long, see this discussion on the mailing list:
<a href="http://lists.llvm.org/pipermail/llvm-dev/2016-January/093950.html">http://lists.llvm.org/pipermail/llvm-dev/2016-January/093950.html</a>, but for now
the consensus seems to be that bools need to be declared as 8 bit in the debug
info.</pre>
