to_string functions are massive and probably shouldn't always be inline.

The to_string set of functions are quite large and since they are always inline, using them on multiple functions on multiple files explodes the binary size. It also makes it hard to debug if you use a de compiler as part of your debugging tools. I suggest changing the attributes to be a non inlined weakly declared/defined symbol instead. That way, during the linking step, only one of the symbols will be arbitrarily used and the rest of the duplicates will be discarded.

@Emimendoza That's an interesting aspect to keep in mind. We did some testing on that issue and it seems, those functions tend to not be inlined, but kept as separate functions. Probably due to their size.
Do you have some setup or program that produces multiple inlined instances of (some of) those functions?
