Fix bug in fixed-point handling

Alexandre Oliva found a bug in gdb's handling of fixed-point -- a
certain Ada fixed-point type would be misintepreted.  The bug was that
the DW_AT_small looked like:

 <1><13cd>: Abbrev Number: 16 (DW_TAG_constant)
    <13ce>   DW_AT_GNU_numerator: 1
    <13cf>   DW_AT_GNU_denominator: 0x8000000000000000

... but gdb interpreted the denominator as a negative value.
