    libproc_macro: Add drop function to Literal struct
    
    Add a drop function to clean internal fields of a Literal struct.
    
    ChangeLog:
    
            * libgrust/libproc_macro/literal.cc (Literal__drop): Replace
            implementation by a call to Literal::drop.
            (Literal::drop): Add drop implementation.
            * libgrust/libproc_macro/literal.h: Add function prototype.
