This series adds support for a GLSL IR level and TGSI (OpenGL/st) level caches.
There are a few small bug fixes and a little bit of restructuring to the GLSL IR patches to make things work for Gallium drivers vs just i965 previously, but nothing too major. The biggest change is patch 35 which changes the mesa cache directory to be more structured allowing us to not fallback to recompiles at draw time if we realise a cache item was created with an old version of Mesa. Patch 36 also cleans up old cache files so we shouldn't get into a possition were we are constantly evicting cache items because its never cleaned out. Even with the new directory structure I've still left in the code that adds the Mesa version string to cache items because users can do things like override the OpenGL version which will change the output (in future we might want to just add this as part of the sha1 input). This series does not include the patch that adds cache support to the radeonsi backend, the main reason for this is that llvm currently doesn't allow the version to be queried at runtime (as far as I'm aware) although it seems like other are interested in this feature [1] so I will follow up on that. The reason we don't just use the build time like radv is that we will want something consistent accross distros to enable distribution of precompiled shaders. Without the radeonsi patch min fps still goes up around 4 fps in the Shadow of Mordor benchmark (although the stalls are still very noticeable). I should also point out that this enables a tgsi level cache for r600, but I haven't tested this myself and lack the hardware. Also any other Gallium driver that uses TGSI should also be able to enable support. Please review.
