    glsl: implement switch flow control using a loop

    Patch removes old variable based logic for handling a break inside
    switch. Switch is put inside a loop so that existing infrastructure
    for loop flow control can be used for the switch, now also dead code
    elimination works properly.

    Possible 'continue' call inside a switch needs now special handling
    which is taken care of by detecting continue, breaking out and calling
    continue for the outside loop.

    v2: remove one unnecessary ir_expression (Curro)

    Fixes following Piglit tests:

       fs-exec-after-break.shader_test
       fs-conditional-break.shader_test

    No Piglit or es3conform regressions.
