Revert templates to old behavior.
While emitting a template instantiation only once is good for compile times
and binary sizes, it doesn't work with linkonce linkage as inlined function
bodies could be discarded. Since we don't want to inhibit inlining, templates
are reverted to the previous behavior, where an instantiation is emitted for
each module using it.
In the future, a custom inlining pass may allow us to switch back to
common/weak linkage and reenable smart template instance emission.
