- Instruction heap is currently heavily used as every kernel copies ISA into
it.
- It dries out very fast and each change to new heap requires whole pipeline
drain that prevents concurrency
- Problem is even larger when sip kernel is used as it limits the total heap
size
- In order to maximize heap re-use and to limit the count of pipeline drains
this change introduces new minimal size for instruction heap 512 KB.

- In various scenarios code was not programming the max heap size correctly
- It was possible for SSH to overcome the limit
- Size was programmed smaller then it really was, which resulted in smaller
reuse, which led to SBA reprogramming which led to lower performance in ooq
scenarios
- This change fixes the heap size programming by always utilizing full
allocation size and always limiting SSH at proper value

- It should use thread count not EU count.
- change variable name to reflect that we work on sublices.
- fix test description, add missing test
- change hasBarrier variable to be boolean

- Call waitForTaskCountAndCleanAllocationList with latest flushed task count
to reflect what was actually sent to HW.
- refactor cleanAllocationList to waitForTaskCountAndCleanAllocationList

- Fix SUPPORT_X and TESTS_X flags in cmake
Previously it was possible to enable TESTS_X with disabled SUPPORT_X
- Remove genX dirs from include paths

- Prevents destruction of MemObj while it may still be in use.
- Add UNRECOVERABLE to check whether object is deleted while having
dependencies, fix all problems is tests due to that fact.
- Fix special queue setting, clean interfaces.

- due to the fact that device mutex was obtained to prevent threaded access to
image there was a problem when other thread was also doing readImage call
That thread got read Image kernel mutex first and then it was acquiring device
mutex, which was taken by other thread doing mapImage call.
- In current code device mutex is not taken to service mapImage call, instead
image is being guarded by its own mutex.

- This causes event tree update if virtual event is holding commands or
callbacks
- That causes race between other threads that may be updating the tree
