Bytecode in question
This one was caught by pypy folks. It looks like some internal stuff was
corrupted. valgrind is clean. Steps to reproduce:
opt foo.bc -inline -tailduplicate -scalarrepl -gvn -instcombine -simplifycfg
Bugpoint wasn't be able to reduce stuff: it was fooled by another assertion
caught after removing of global initializers.
