Testcase to reduce
The attached testcase fails to reduce due to producing invalid IR that is
missing the ret instruction. It initially started reducing, but eventually has
the incorrect failure signature due to parse errors in the text IR produced by
the previous reduction steps. Running llc, the interestingness script prints
parse errors:
