[dxso] Fix for illegal OpCompositeConstruct while translating Crs opcode

Browse Source 
During the translation of the Crs opcode to SPIR-V there is an assumption that the result type is a composite type. This is not always true. If the result is a scalar type the translation adds an OpCompositeConstruct with a scalar result type. This is a spec violation.

This change checks if the result type is a composite type and does not add the OpCompositeConstruct in case of scalar types.
