[RISCV] Fix instruction requires the following: 'D'/'F'/'M'

Reviewed by Yusuke Suzuki.

This is a llvm bug, passing `-march=riscv64gc -cpu=lp64d` from clang
will lost after it got llvm side. So we have to set arch here.

This issue is caused by a bug in llvm, and I think this PR is currently harmless.
Once the bug in llvm is fixed, and the patch is ported to old versions, this change here will no longer be needed

To be honest, I'm not very confident because it has some relationship with llvm. Maybe we should wait for now and check it again after llvm/llvm-project#97685 is merged.

You need to enable it only for RISCV64.
