Delete dead code on last optimization step, otherwise ASM will split exception table on it.

ASM has logic that splits exception tables in MethodWriter.computeAllFrames:
     // Loop over all the basic blocks and visit the stack map frames that must be stored in the
     // StackMapTable attribute. Also replace unreachable code with NOP* ATHROW, and remove it from
     // exception handler ranges.
     ...
     firstHandler = Handler.removeRange(firstHandler, basicBlock, nextBasicBlock);
     ...
