Namespace ambiguity between foo.< and foo._LT_

[jeaye]

@frenchy64 put up a fix for this, but it leads to two new issues:

1. If both of those become their own ns, we need to store the atomic counter outside of the ns so that two ns with the same munged symbol name share the same counter. A synchronized map in rt context would do.
2. The module load fn for both of these would have the same symbol, so we need a way to handle separating them. Perhaps we can make them unique and then attach an attribute to the object file which says the load fn name. Or maybe include a global string with internal linkage which hold that value and we can pull it out of the object file? Will take some research.
