[Mesa-dev] [PATCH 3/4] r600g: remove unused sbcl env. variable

[Constantine Kharlamov]

sb-based optimization was only used for older LLVM, whose support was
removed in 100796c15c3a1467d03abc424e6f1494da02f376 "gallium/radeon:
drop support for LLVM 3.5". As of now sbcl variable doesn't do anything.

     There are new flags:
 
     -   **nosb** - Disable sb backend for graphics shaders
-    -   **sbcl** - Enable optimization of compute shaders (experimental)
     -   **sbdry** - Dry run, optimize but use source bytecode -
         useful if you only want to check shader dumps
         without the risk of lockups and other problems
