Use native scalar `fma` instruction (#1267)
Cranelift 0.87 now supports lowering `fma` as a libcall on x86 [0]. With 0.88 enabling the native x86 instruction under the `has_fma` flag. aarch64 and s390x already support this as a native instruction, so it's nice that we emit it for those. We can't lower the SIMD version using the `fma` instruction since the lowering can fail if the x86 `has_fma` flag is not enabled. Cranelift doesn't yet know how to fallback for these cases [0]: https://github.com/bytecodealliance/wasmtime/commit/709716bb8e6adaf7e65f3497168af23ce0cf09ef
