glsl: Add a new ir_builder::dotlike() function.
dotlike() uses ir_binop_mul for scalars, and ir_binop_dot for vectors.
When generating built-in functions, we often want to use regular
multiply for scalar signatures, and dot() for vector signatures.
ir_binop_dot only works on vectors, so we have to switch opcodes,
even if the code is otherwise identical. dotlike() makes this easy.
