Subject: r600 : check in shader code test enable flag: if flag
 R600_ENABLE_GLSL_TEST defined, IL shader code will goto r600 assembler. The
 test base is /mesa/progs/glsl/brick, and changes shader code in
 CH06-brick.frag/vert to test different logic op combination.
 (if,else,while,function,...). The stack depth code is not in yet, so it is
 hard coded now. So complex code would not run (such as things like 8 loops
 embeded loop in loop).
