Modpaths need to be in the proper scope in order to be available to
vpi functions. The code generator manages that by writing the modpath
records with scope switch functions. Batch the modpath records at the
end of the structural stuff so that the scope switching doesn't cause
trouble.
Also seperate the modpath code into its own source file.
