[PATCH][LTO] Re-set boolean_type_node in free_lang_data

[Eric Botcazou]

> You mean like Ada does?

Ada has only one boolean type so there isn't much leeway.  It will need to be 
changed but that's not straightforward.

But my question was serious: if Fortran has all kinds of different precision 
boolean types, why not decide that boolean_type_node is the Right One?  That 
would avoid frobbing it for other languages.
