[Mesa-dev] [PATCH 19/30] i965/fs: Pass single backend_shader argument to the fs_live_variables constructor.

[Francisco Jerez]

This removes the dependency of fs_live_variables on fs_visitor.  The
IR analysis framework requires the analysis result to be constructible
with a single argument -- The second argument was redundant anyway.
