[llvm] [VP][RISCV] Add a vp.load.ff intrinsic for fault only first load. (PR #128593)

[Florian Hahn via llvm-commits]

Would it be possible to also add a generic lowering like for the other VP intrinsics? I think in general we try to complement intrinsics with a default lowering, to avoid crashes in the backends, like https://llvm.godbolt.org/z/89sf8WbYs
