[Piglit] [PATCH] tests/spec/glsl-1.30: add tests for integer sign() function

[Ilia Mirkin]

What's wrong with

generated_tests/spec/glsl-1.30/execution/built-in-functions/fs-sign-ivec4.shader_test

[fragment shader]
uniform ivec4 arg0;
uniform ivec4 expected;

void main()
{
  ivec4 result = sign(arg0);
  gl_FragColor = result == expected ? vec4(0.0, 1.0, 0.0, 1.0) :
vec4(1.0, 0.0, 0.0, 1.0);
}
