gdb: Convert language_data::la_range_check to a method

Browse source 
Convert language_data::la_range_check member variable to a virtual
method language_defn::range_checking_on_by_default.

Where the previous member variable was of type 'enum range_check', the
new member function returns a boolean that selects between range
checking being on or off.  This removes the possibility of a language
having its default be the third enum state, range_check_warn, which
no language currently used.

This all makes sense I think, the language's true/false provides the
default when the global 'set check range' is set to 'auto'.

There should be no user visible changes after this commit.
