IGC only accepts three values for -ze-opt-level, 0, 1 and 2, however dpcpp has at least four options, O0, O1, O2 and O3.
Right now we decided to map O1 and O2 to -ze-opt-level=1, but we have determined that this is not the best for user experience and may defy user expectation, and actually produces worse code than specifying nothing because IGC uses ze-opt-level=2 if nothing is specified.
