Reid Kleckner 85e933eefe [IR] Keep a double break between functions when printing a module
This behavior appears to have changed unintentionally in
b0e979724f2679e4e6f5b824144ea89289bd6d56.

Instead of printing the leading newline in printFunction, print it when
printing a module. This ensures that `OS << *Func` starts printing
immediately on the current line, but whole modules are printed nicely.
