Add message buffer space available coherency test (#515)

Browse source 
* Introduce tasks that test the coherency of the reported space available in a message buffer from two separate tasks.  Designed to highlight the issue reported in https://github.com/FreeRTOS/FreeRTOS-Kernel/pull/264
Introduce configRUN_ADDITIONAL_TESTS which must be set to 1 to run the new tests.  That is because the new tests got added to an existing standard demo file and smaller platforms may not have the resources to run them.
Set configRUN_ADDITIONAL_TESTS to 1 in the MSVC and IAR/QEMU project so both project run the new test.
Also add missing 'volatile' qualifier in the IAR/QEMU project on some register accesses.

* Update xAreMessageBufferTasksStillRunning() to report errors from the new message buffer size coherency tests.
