These include:
- {i32,i64}.trunc_{f32,f64}_{s,u}
According to our new benchmarks this optimization improves performance of those listed instructions by 6000% (a.k.a x60). LOL

According to our new benchmarks this optimization improves performance of all 8 float to int Wasm truncation instructions by roughly 6000% (a.k.a. 60 times faster).
This also gets us rid of the
num-rationalcrate dependency fromwasmi_corewhich reduceswasmifresh release build time by roughly 23% and reduces Wasm file size ofwasmi_corecrate by roughly 5%.Nuff said ...
