[drlvm][jit][opt] Spillgen ignores intitial constrains sometimes
----------------------------------------------------------------

                 Key: HARMONY-5425
                 URL: https://issues.apache.org/jira/browse/HARMONY-5425
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Mikhail Fursov
            Assignee: Mikhail Fursov


I found that in some scenarios with high register pressure (I can't neither publish the sources
or create a microtest) spillgen reassigns an operand from callee-save register to caller-save
making its value invalid after a CALL

The problem method was originally found in a method: org/apache/harmony/awt/gl/Crossing::intersectCubic

I apply the patch that fixes the problem.
