8351348: x86_64: remove redundant supports_float16 check

[Hamlin-Li]

Hi,
Can you help to review this simple patch?
supports_float16() is invoked in is_intrinsic_available -> is_intrinsic_supported, so there is no need to call it explicitly.

Thanks

I am on fence for this. You can consider it as "short-cut" to quickly check availability of feature. It will be called 2 times without it (I am not sure calls will be inlined and optimized).
