Have ptype handle types declared pragma Unchecked_Variants.

When a type is marked with pragma Unchecked_Variants, ptype did not print
variants having a single component, since the compiler produces incorrect
debugging output for such cases.  With this patch, we special-case these
components so that they print.

Changelog:

    * gdb/ada-typeprint.c (print_selected_record_field_types): New function,
    incorporating and generalizing print_record_field_types.
    (print_record_field_types): Change return value and update comment.
    Re-implement using print_selected_record_field_types.
    (print_choices): Print "=>" here.
    Handle case of unencoded variant branch.
    (print_variant_clauses): Reformat comment.
    Special-case unencoded variant branch.

Replace wild_match with faster version and modify its interface.

This new version of wild_match is comparable in speed to strcmp_iw, and has
the same signature and same return value for equal names.

gdb/ChangeLog:
    * ada-lang.c (wild_match): Reimplement.
    Change API to eliminate unused length argument, reverse arguments and
    make 0 the 'true' return value.
    (advance_wild_match): New auxiliary function for wild_match to improve
    readability.
    (ada_match_name, ada_add_block_symbols): Use new API for wild_match.
    * psymtab.c (ada_lookup_partial_symbol, map_ada_symtabs): Use new
    API for wild_match.
    * symfile.h (map_ada_symtabs): Modify declaration to use new API for
    wild_match.
    * dwarf2read.c (dw2_map_ada_symtabs): Ditto.

[Ada] array and bounds in fat pointer can be a stub

This patch adds handling of the case when a fat pointer has the
P_ARRAY and/or P_BOUNDS fields defined as a stub.  In that case,
this stub needs to be resolved.

There are two issues:

  . First, making sure that the resolution takes place itself.
    That's the change to ada_check_typedef.

  . Make sure that the type returned after resolution is not itself
    a typedef.  This is the change to ada_check_typedef.

gdb/ChangeLog (Jerome Guitton, Joel Brobecker):

        * ada-lang.c (desc_bounds): Add handling of the case where
        the P_BOUNDS field is a pointer to a stub.
        (desc_data_target_type): Same for P_ARRAY field.
        (ada_check_typedef): Strip the typedef layers from the type
        found by ada_find_any_type.
