I can reproduce this failure mode if I add a dummy main to vvadd.ll
and try to run lli on it using the *old* JIT. When I add the
"-use-mcjit" option the snippet compiles successfully.

The old JIT is known to be pretty much non-functional on ARM, so
that's not surprising. The best option is to switch python over to the
MCJIT (looking in tools/lli/lli.cpp should give hints on how).
