JDK-8318228 - RISC-V: C2 ConvF2HF
Description
There are several areas where improvements can be made:
1. test should not exit early before all test cases have run.
2. some output hide the data details, which should be printed out to help debug any potential issues, e.g. currently it could output some log like below in case of wrong implementation of a ConvF2HF intrinsic:
`Inconsistent result for Float.floatToFloat16(NaN/ff802000): fc01 != fc01`, which is rather confusing, not helpful. Suggested output would be: `Inconsistent result for Float.floatToFloat16(NaN/ff802000): fc01(64513) != fc01(-1023)`
Comments
The tests are added by JDK-8302976, the 17u and 11u backport depends on this, will do this when it's backported.

Fix request [21u] I backport this for parity with 21.0.3-oracle. No risk, only a test change. Clean backport. Test pass. SAP nightly testing passed.
