Description

https://github.com/JuliaLang/julia/pull/47546 made BigFloat(::Float64) about 2x faster, but basically the same optimization could be done for the common Integer types (Base.BitInteger64), Base.IEEEFloat and Rational (where the denominator is a power of 2).

Contributor guide

Research direction
Study the optimization for Float64 in PR #47546 and generalize it to other types: BitInteger64, IEEEFloat, and Rational with power of 2 denominator.
