st/glsl_to_tgsi: fix ir_assignment hack doing bad things for doubles
This hack for fixing gl_FragDepth apparantly caused a GLSL shader
outputting a single double to try and output a dvec4, but we hadn't
assigned outputs for the secondary bit.
This avoids going into the hack code for scalar doubles.
