    PR 15231: import bare DW_TAG_lexical_block

    Local variables in lambdas are not accessible
    https://sourceware.org/bugzilla/show_bug.cgi?id=15231

    GDB: read_lexical_block_scope
      /* Ignore blocks with missing or invalid low and high pc attributes.  */
    [...]
      if (!dwarf2_get_pc_bounds (die, &lowpc, &highpc, cu, NULL))
        return;

    But sometimes there is:

    FAIL: gcc-5.3.1-6.fc23.x86_64
     <2><92>: Abbrev Number: 11 (DW_TAG_lexical_block)
     <3><9c>: Abbrev Number: 13 (DW_TAG_structure_type)
        <9d>   DW_AT_name        : (indirect string, offset: 0x3c): <lambda()>
        [...]

    Where DW_TAG_lexical_block has no attributes.  Such whole subtree is
currently
    dropped by GDB while I think it should just import all its children DIEs.

    It even XFAIL->XPASSes gdb.ada/out_of_line_in_inlined.exp:
        commit 0fa7fe506c242b459c4c05d331e7c7d66fb52390
        Author: Joel Brobecker <brobecker@adacore.com>
            out of line functions nested inside inline functions.
    So I have removed that xfail.
