intel/vec4: Fix nir_op_b2[fi] with 64-bit result
This is valid NIR but you can't actually hit this case today. GLSL IR
doesn't have a bool to double opcode; it does f2d(b2f(x)). In SPIR-V we
don't have any to/from bool conversion opcodes at all. However, the
next commit will make us start generating it so we should be ready.
