[LLVMdev] Jump threading pass bug

[Argyrios Kyrtzidis]

If I use the jump threading pass on the attached IR:

$ opt before.ll -jump-threading -o - | llvm-dis -o after.ll

 a big chunk gets removed, a chunk that is actually necessary. ('before.ll' passes the test in webkit, while 'after.ll' fails)

Can someone take a look ?
