This commit adds lowerings to the AArch64 backend for the `fmls` instruction which is intended to be leveraged in the relaxed-simd proposal for WebAssembly. This should hopefully allow for a teeny-bit-more efficient codegen for this operator instead of using the `fmla` instruction plus a negation instruction.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
