CPU ABI improvements (#1056)

* WIP: Improving CPU performance/ABI

* Optionally output code on CPU for groupThreadID and groupID.

* Added ability to set compute dispatch size on command line for render-test.
Dispatch compute tests taking into account dispatch size.
Added test for semantics are working.

* Test using GroupRange.

* Fix problem with adding \n for externa diagnostic - to do it if there isn't a \n at the end. Change the ouput order (put result before) so last value is diagnostic string.
