This uses the recently-added disk_cache.c to write out the final<br>
linked binary for vertex and fragment shader programs.<br>
<br>
This is based off the initial implementation done by Carl Worth.<br>
<br>
v2:<br>
* Squash 'i965: add image param shader cache support'<br>
* Squash 'i965: add shader cache support for pull param pointers'<br>
* Sustantially simplified by a rework on top of Jason's 2975e4c56a7a.<br>
* Rename load_program_data to read_program_data. (Jason)<br>
