:wave: Hey,

This PR implements SIMD fcmp for RISC-V. This is a lot simpler than icmp since we don't have as many instructions to implement. Furthermore half of the rules are implemented with mask operations and other rules, so we save significant amounts of work by reusing the preexisting rules.

All of these lowerings are based on what LLVM generates.
