    glsl: fix broken +=, -=, *=, /= operators
    
    These functions need to return the final computed value.
    Now expressions such as a = (b += c) work properly.
    Also, no need to use __asm intrinsics in these functions.  The resulting
    code is the same when using ordinary arithmetic operators and is more legible.

    mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.
    
    There was a note in state.c about _Active deserving to die, and there were
    potential issues with it due to i965 forgetting to set _UseTexEnvProgram.
    Removing both simplifies things.

    glsl: loop unroll adjustments
    
    Add a "max complexity" heuristic to allow unrolling long loops with small
    bodies and short loops with large bodies.
    
    The loop unroll limits may need further tweaking...

    glsl: implement loop unrolling for simple 'for' loops
    
    Loops such as this will be unrolled:
      for (i = 0; i < 4; ++i) {
          body;
      }
    where 'body' isn't too large.
    
    This also helps to fix the issue reported in bug #19190.  The problem there
    is indexing vector types with a variable index.  For example:
      vec4 v;
      v[2] = 1.0;  // equivalent to v.z = 1.0
      v[i] = 2.0;  // variable index into vector!!
    
    Since the for-i loop can be unrolled, we can avoid the problems associated
    with variable indexing into a vector (at least in this case).
