This allows JVMCI compiler to comply with `-XX:DisableIntrinsic`, `-XX:ControlIntrinsic`, `-XX:-UseXXXIntrinsic`, and is essential for running test that depends on these flags, e.g., `java/lang/Float/Binary16ConversionNaN` that returns different result in the interpreter with `-XX:DisableIntrinsic=_float16ToFloat,_floatToFloat16`.
