    nir/algebraic: Use value range analysis to eliminate useless unary ops

    Sandy Bridge is the big winner because it lies at something of a
    crossroads.  It supports a fairly high OpenGL version, and it still has
    the old style math box.  The high OpenGL version means a lot more
    shaders can run on it.  The old style math box means extra moves are
    necessary to resolve source modifiers on operands to complex math
    instructions like COS, SQRT, and RCP.
