Comment (by harendra):

 Multiple data points suggest that it does not look like a memory issue.
 However, we could workaround the bug by splitting the long list. So it
 looks like `opt` cannot handle the code generated by GHC for a list that
 is too long. If someone knowledgable about the llvm/IR can pinpoint the
 issue or raise a bug with llvm upstream that will be helpful. This was
 working with an earlier version of GHC/LLVM so it is possible that this
 can be fixed easily.

 If it is non-trivial to fix for llvm/opt we can just close it and just
 avoid long lists. In that case, maybe GHC can issue a warning about long
 list so the the programmer can take appropriate action. In this particular
 case the list holds static data to initialize a bitmap, maybe this is just
 a rare use case for such a long list.
