[Mesa-dev] [PATCH] i965: Increase BRW_MAX_UBO to 15.

[Kenneth Graunke]

I believe that DirectX offers 16 UBOs, with one reserved for special
purposes.  This means that the practical lower bound is 15, even if
OpenGL only mandates 12.

Without this, Shadow of Mordor shaders fail to work because of limit
checking around GL_MAX_UNIFORM_BUFFER_BINDINGS.

Shadow of Mordor also needs tessellation, so backporting this wouldn't
help the game any.
