getSVEType built the bf16 and f32 vectors from mlir::Builder's
getBF16Type() and getF32Type(), which return builtin MLIR types.
!cir.vector only accepts CIR element types, so an assertions build
aborts in VectorType::get and a release build creates an invalid type.
Use getBfloat16Ty() and getSingleTy(), as the f16 and f64 cases do.
