[Mesa-dev] [PATCH v3 12/34] main: Add driver cache blob fields to gl_program

[Jordan Justen]

These fields can be used to optionally save off a driver blob with the
program metadata. For example, serialized nir, or tgsi.

v3:
 * Rename serialized_nir* to driver_cache_blob*. (Tim)
 * Free memory. (Jason)
