We've exploited test data class instructions for `f32` `f64` v2f64` and `v4f32`. This patch unifies the LLVM intrinsic into the same `ppc_test_data_class` and add support for 128-bit precision float values using `xststdcqp`.

Vector versions of the intrinsic can't be unified because they return vector int instead of int.
