The current implementation looks for array dereferences on gl_FragData and
immediately then proceeds to lower them, however this is not enough because
we can have array access on vector variables too, like in this code:
out vec4 color;
void main()
{
int i;
for (i = 0; i < 4; i++)
color[i] = 1.0;
}
Fix it by making sure that the actual variable being dereferenced is an array.
