Tamás Danyluk 248b85344b [SCCPSolver] Speed up SCCPSolver by avoiding repeated work list elements ...

If a value is already the last element of the worklist, then I think that we don't have to add it again, it is not needed to process it repeatedly.

For some long Triton-generated LLVM IR, this can cause a ~100x speedup.
