    [gdb/testsuite] Add target board debug-types

    This patch adds a target board debug-types that switches on
    -fdebug-types-section by default.

    This -fdebug-types-section option is a gcc option that enables the
generation
    of a .debug_types section, which is only effective for DWARF version 4.

    There are two other boards that enable this: dwarf4-gdb-index and fisso=
n,
but
    while those test some meaningful combination of options, this board is
    intended to test only -fdebug-types-section.

    Current results with gcc 7.5.0 are:
    ...
     =3D=3D=3D gdb Summary =3D=3D=3D

     # of expected passes            75832
     # of unexpected failures        2841
     # of expected failures          130
     # of known failures             75
     # of unresolved testcases       22
     # of untested testcases         37
     # of unsupported tests          83
    ...
