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.
Why not just make dot() do this?
I wasn't sure how I felt about dot() returning something other than
ir_binop_dot. But it kind of makes sense, so if people would prefer
that, I'm fine with doing that instead.
