A significant CPU performance bottleneck in mesa GL is refcounting atomics: even with the current pinning attempts, eliminating them can yield huge performance gains (easily verified by running drawoverhead with return false at the top of pipe_reference_described()). This is a proof of concept for removing refcounts from gallium objects, namely sampler views and resources. Sampler views were smaller in scope, so I started there. This MR alone is not expected to noticeably affect performance, though if applied to all drivers/frontends, it would enable a bunch of code deletion for crazy samplerview refcounting hacks currently used to try circumventing the existing overhead.
