[drlvm][jit]problems with allocation for dead-def and jump instructions in spillgen
-----------------------------------------------------------------------------------

                 Key: HARMONY-4309
                 URL: https://issues.apache.org/jira/browse/HARMONY-4309
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Ivashin Sergey
         Attachments: spillgen.patch

This patch fixes two issues in spillgen:

1) Allocation register to dead-definition does not mark the register as occupied if it was
obtained by evict operation.
2) Allocation register to complex operand of jump instruction may cause inserting mov instruction
after jump.

Both these problems are rare and hard to reproduce.
