Ilja Iskovs 66bfcdcb43 [arm64][wasm-simd] Use Fcm(0) for floating point comparison with zero.
Use an immediate zero operand for floating point comparison nodes when
possible. This results in up to 20-25% runtime improvement in some
microbenchmarks, as well as 1-1.5% runtime improvement in some
real-use benchmarks on Cortex-A55 and Neoverse N1.
