Mesa compiles GLSL code with its own compiler.  It produces an IR 
which is then translated into several different instructions sets 
depending on the driver.  LLVM is not involved in this.

For OSMesa, the IR is translated into Mesa internal GPU-like 
instruction set which is executed with a simple interpreter.
