glsl: Add type predicate to check whether a type contains any opaque types.
And use it to forbid comparisons of opaque operands. According to the
GL 4.2 specification:
> Except for array indexing, structure member selection, and
> parentheses, opaque variables are not allowed to be operands in
> expressions.
