So that we can pass pointers to individual array entries around.

* The 'type' parameter identifies whether the shader state contains TGSI
* tokens, etc. If the driver returns 'PIPE_SHADER_IR_TGSI' for the
* 'PIPE_SHADER_CAP_PREFERRED_IR' shader param, the ir will *always* be
* 'PIPE_SHADER_IR_TGSI' and the tokens ptr will be valid. If the driver
* requests a different 'pipe_shader_ir' type, then it must check the 'type'
* enum to see if it is getting TGSI tokens or its preferred IR.
