    [gdb/testsuite] Add xfails for PR gcc/90232
    
    With target board debug-types, we have these FAILs:
    ...
    FAIL: gdb.guile/scm-symtab.exp: test simple_struct in static symbols
    FAIL: gdb.python/py-symtab.exp: test simple_struct in static symbols
    ...
    due to PR gcc/90232, as explained in commit 15cd93d05e8 "[gdb/symtab] Handle
    struct decl with DW_AT_signature".
    
    Marks these as XFAILs.
    
    Tested on x86_64-linux.
    
    gdb/testsuite/ChangeLog:
    
    2020-04-29  Tom de Vries  <tdevries@suse.de>
    
            * lib/gdb.exp (debug_types): New proc.
            * gdb.guile/scm-symtab.exp: Add xfail for PR gcc/90232.
