4de3f5d7 - [mypyc] Make explicit conversions i64(x) and i32(x) faster (#14504)

[mypyc] Make explicit conversions i64(x) and i32(x) faster (#14504) These behave the same as `int(x)` and we want them to be no slower than the corresponding `int` conversions. Optimize them for bool, float, str and RInstance arguments. Work on mypyc/mypyc#837.
