Use correct shader local memory size instead of a hardcoded size (#914)

* Use correct shader local size instead of a hardcoded size

* Remove unused uniform block

* Update XML doc

* Local memory size has 23 bits on maxwell

* Generate compute QMD struct from nv open doc header

* Remove dummy arrays when shared or local memory is not used, other improvements
