[drlvm][jit][opt] type merge for stack vars in prepass is too restrictive
-------------------------------------------------------------------------

                 Key: HARMONY-4702
                 URL: https://issues.apache.org/jira/browse/HARMONY-4702
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: All
            Reporter: Pavel Ozhdikhin


VarIncarnations of stack variables of different types are not merged at joining edges, even if their types are compatible. This may lead to incorrect promotion of the stack var to variable at some CFG point and to the crash during the compilation. The bug was caught on a complex Jython scenario with dynamic class generation.
