- * Load operations pull data from some piece of GPU memory.  All load

- * take a base+offset pair where the base (const_index[0]) gives the location
- * of the start of the variable being loaded and and the offset source is a
- * offset into that variable.
- *
- * Some load operations such as UBO/SSBO load and per_vertex loads take an
- * additional source to specify which UBO/SSBO/vertex to load from.
- *
- * The exact address type depends on the lowering pass that generates the
- * load/store intrinsics.  Typically, this is vec4 units for things such as
- * varying slots and float units for fragment shader inputs.  UBO and SSBO
