This PR adds handling of the numthreads attribute for compute shaders, as well as a general infrastructure for returning attribute values from acceptAttributes, which may be needed in other cases, e.g, unroll(x), or merely to know if some attribute without params was given. A map of enum values from TAttributeType to TIntermAggregate nodes is built and returned. It can be queried with operator[] on the map. In the future there may be a need to also handle strings (e.g, for patchconstantfunc), and those can be easily added into the class if needed. New test is in hlsl.numthreads.comp.
