log1p getting overwritten

[ExpandingMan]

There seems to be an extra method from another library here. At least on 0.7 this results in the methods for log1p getting overwritten. Would it be ok to either delete this line or, if it's needed for 0.6, move it to within the conditional?

Yes, we should just wrap it in a conditional e.g.

if is_version_that_doesnt_need_to_reference_libm(VERSION)
    @define_diffrule Base.log1p(x) = ...
else
    @define_diffrule Base.Math.JuliaLibm.log1p(x) = ...
end

I don't know what that predicate is off the top of my head, but it seems like just Base.log1p works for v0.7.
