Hi,

During the replacement of Vector API nodes, a node may become dead because its control dies. In that case, we will throw an AssertionError because we try to find a dead node in a node map. As a result, we should skip dead nodes while doing the replacement. Unfortunately, I cannot manage to make a unit test for this issue, it only appears in an OSR compilation with profile, and I believe GraalOSRTestBase clears the profile before compilation.

Please share your thoughts, thanks a lot.
