Note: when intrinsic is not implemented on all platforms, it would need #ifdef`d native implementation. Ideally there will be very few of those.

IIRC this will be problematic on RISC-V since it lacks simple instructions for most atomics even with the extension.

Moving to codegen-coreclr. This would require JIT work to happen and simplifying the managed API can be trivially done if/when that happens.
