[Optimize Instructions] Combine reinterprets, loads and stores (#4006)
Fixes #3973 Loads: f32.reinterpret_i32(i32.load(x)) => f32.load(x) f64.reinterpret_i64(i64.load(x)) => f64.load(x) i32.reinterpret_f32(f32.load(x)) => i32.load(x) i64.reinterpret_f64(f64.load(x)) => i64.load(x) Stores: f32.store(y, f32.reinterpret_i32(x)) => i32.store(y, x) f64.store(y, f64.reinterpret_i64(x)) => i64.store(y, x) i32.store(y, i32.reinterpret_f32(x)) => f32.store(y, x) i64.store(y, i64.reinterpret_f64(x)) => f64.store(y, x) Also optimize reinterprets that are undone: i32.reinterpret_f32(f32.reinterpret_i32(x)) => x i64.reinterpret_f64(f64.reinterpret_i64(x)) => x f32.reinterpret_i32(i32.reinterpret_f32(x)) => x f64.reinterpret_i64(i64.reinterpret_f64(x)) => x
