Comment (by alexcrichton):
I just posted a comment on the bug report with a much more minimal test
case (only a few hundred KB!), it only took many cpu hours to extract :)
From here I'm still trying to reduce it further to increase the likelihood
that someone from LLVM can help fix (I'm not so good at LLVM internals).
This test case is small enough though that it may be pretty reasonable to
bisect LLVM itself with. Dealing with a bitcode file across that many LLVM
revisions may be pretty difficult though, so bisection likely won't be
trivial.
