These values are unsigned, but the temporaries are always assumed to be in float
representation, and the temps values will be re-interpreted as integers when
needed. Hence above values must not be value-converted to float but the
bit-representation must be maintained when they are stored in a temp register.

Don't use the shader key when forcing it.
Changing a shader key within vrend_create_shader will always force
virglrenderer to recreate the shader the next time it is looked up, so
memory usage will grow and performance will go down.
Also it is actually not needed if with each emitted back color also has a
corresponding front color is emitted. So restrict forcing two-sided coloring
to the cases where a back color is emitted without a front color, and don't
change the shader key.

Sometime the shader key "color_is_twosided" is not set, but the vertex
shader only emits a back color and the fragment shader expects a front
