[C++] Log functions don't have int kernels

[asfimport]

I've been writing R bindings for the log functions implemented in this PR: #10567

They work when the inputs are floats, but when the input is an int32 I get the following error:

NotImplemented: Function ln_checked has no kernel matching input types (scalar[int32])

Ah, sorry, during the review for either trig or log functions it was questioned whether having integer variants was useful, so I removed them. Maybe I can have it auto-promote integer arguments to floating point ones?

Sounds like a great solution to me! :)
