Description
Update the assembly code used in the Cortex-A9 port to ensure stack alignment before calling vTaskSwitchContext() in case user code added to the function (maybe via a trace macro or other mechanism) requires the more strict alignment. That would be the case if, as an example, floating point instructions were used.
Test Steps
The self monitoring integration tests have been running for several weeks with no issues.
