What about making the check stronger here by only allowing `operands.size()` of 2 and 3. I don't think [spec](https://registry.khronos.org/SPIR-V/specs/unified1/SPIRV.html#OpTypeFloat) allows any other number of operands. The message below also should be changed - maybe: `"OpTypeFloat must have bitwidth parameter and optional floating point encoding"`.
