Added few more stubs so that control reaches to DestroyDevice().

- * Computes a conservative start/end of the live intervals for each virtual GRF.
- *
- * We could expose per-channel live intervals to the consumer based on the
- * information we computed in vec4_live_variables, except that our only
- * current user is virtual_grf_interferes().  So we instead union the
- * per-channel ranges into a per-vgrf range for vgrf_start[] and vgrf_end[].
- *
- * We could potentially have virtual_grf_interferes() do the test per-channel,
- * which would let some interesting register allocation occur (particularly on
- * code-generated GLSL sequences from the Cg compiler which does register
- * allocation at the GLSL level and thus reuses components of the variable
- * with distinct lifetimes).  But right now the complexity of doing so doesn't
- * seem worth it, since having virtual_grf_interferes() be cheap is important
- * for register allocation performance.
