TestSubNodeFloatDoubleNegation.java fails with native Float16 support

      The IR test TestSubNodeFloatDoubleNegation.java fails when the machine it is running on has support for Float16. In that case, the compiler generates two half-float subtractions and an alternative codepath with a normal float subtraction. This was first discovered for RISC-V in JDK-8353665, but also applies to x64 with the feature AVX512-FP16 and needs to be investigated for ARMv8 with FEAT_FP16.
