RFR: 8352897: RISC-V: Change default value for UseConservativeFence

Tue Mar 25 15:55:37 UTC 2025

Hi, please consider.

gcc have stopped emitting io-bits for fences since 13.
And we need to use newer gcc due to other compiler bugs.
Therefore there is no point in letting JIT emit io-bits when the runtime don't have them.

Thanks, Robbin
