Francisco Casas 2d91bd9200 vkd3d-shader/hlsl: Properly lower casts to int for negative numbers.
While it looks complicated, it is what fxc/d3dcompiler does.

A shader as simple as:

    float4 f;

    float4 main() : sv_target
    {
        return (int4)f;
    }

results in the following instructions:

    ps_2_0
    def c1, 0, 1, 0, 0
    frc r0, c0
    cmp r1, -r0, c1.x, c1.y
    add r0, -r0, c0
    mov r2, c0
    cmp r1, r2, c1.x, r1
    add r0, r0, r1
    mov oC0, r0
