This patch fixes the issue reported as PR21807. There was a minor difference in the generated code depending on the -g flag. The cause was that with -g the machine scheduler used a different scheduling strategy. This decision was based on the number of instructions in a schedule region and included debug instructions in that count. This patch fixes the issue in MISched and provides a test.
