compiler: Add SYSTEM_VALUE_IS_INDEXED_DRAW and instrinsics
This VS system value contains if the draw command used to start the rendering was an indexed draw command or a non-indexed one (~0/0 respectively). Useful to calculate the gl_BaseVertex as: (SYSTEM_VALUE_IS_INDEXED_DRAW & SYSTEM_VALUE_FIRST_VERTEX). Reviewed-by: Jason Ekstrand <[email protected]>
