GDB/MI: crash printing "_task" (Ada) argument

In GDB/MI mode, trying to print the arguments of the frame corresponding
to the body of a task ("-stack-list-arguments 1") causes the debugger to
crash.

This is because the compiler adds an implicit argument to that task body
called "_task". mi/mi-cmd-stack.c:list_args_or_locals, which is
responsible for printing the value of our arguments, finds that our
"_task" symbol is an argument, and thus tries to fing the non-argument
equivalent:

              if (SYMBOL_IS_ARGUMENT (sym))
                sym2 = lookup_symbol (SYMBOL_NATURAL_NAME (sym),
                                      block, VAR_DOMAIN,
                                      (int *) NULL);

Unfortunately, it tries using the natural name, which doesn't always
work for Ada parameters, in particular those who are internally-
generated. In our case, The "_task" parameter's natural name is
"<_task>", and that symbol does not exist.  So sym2 is NULL, thus
causing the crash a little later on when trying to dereference it.
We should be using the symbol linkage name in this case, the same
way iterate_over_block_arg_vars already does.

gdb/ChangeLog:

        * mi/mi-cmd-stack.c (list_args_or_locals): For argument symbols,
        use SYMBOL_LINKAGE_NAME to find the corresponding non-argument
        symbol.  Add assertion that sym2 is never NULL.

gdb/testsuite/ChangeLog:

        * gdb.ada/mi_task_arg: New testcase.

Remove language param from name_matcher in struct quick_symbol_functions

The quick_symbol_functions struct contains a field which is pointer
a function which takes another function, called name_matcher, as
its parameter.  This name_matcher currently has 3 arguments, one
of them being the language. This parameter is no longer used, and
thus deleted.

gdb/ChangeLog:

        * symfile.h (struct quick_symbol_functions) [expand_symtabs_matching]:
        Remove language parameter from name_matcher.  Adjust the comment.

Ada: allow unqualified function names in linespecs

gdb/ChangeLog:

        * language.h (symbol_name_match_p_ftype): New typedef.
        (struct language_defn): Replace field la_symbol_name_compare
        by la_get_symbol_name_match_p.

        * c-lang.c, d-lang.c, jv-lang.c, m2-lang.c, objc-lang.c,
        opencl-lang.c, p-lang.c, language.c: Delete field
