#55906 changed `cconvert(Ref{BigFloat}, x::BigFloat)` to return `x.d`, but neglected to do so for other types of `x`, where it still returns a `Ref{BigFloat}` and hence is now returning the wrong type for `ccall`. Not only does this break backwards compatibility (JuliaMath/SpecialFunctions.jl#485), but it also seems simply wrong: the *whole* job of `cconvert` is to convert objects to the correct type for use with `ccall`. This PR does so (at least for `Number` and `Ref{BigFloat}`). (cherry picked from commit 6dca4f4)
