[Ada] Fix unconstrained packed array size

When ada-lang transforms an array descriptor type (an XUP structure)
into an array type, the size of the array type is computed by using
the element size, and multiplying it by the number of elements in
that array. This does not work, however, for packed arrays, where
the *packed* size in bits needs to be used.

This usually does not cause any problem, because we end up reading
more memory than needed.  However, we have observed on LynxOS
a memory error while trying to read the entire array, because
the larger-than-needed read tried to read past the end of the stack
into inaccessible memory.

This patch fixes the problem by correctly computing the array size
in bytes in the case of packed arrays.

gdb/ChangeLog:

        * ada-lang.c (ada_type_of_array): Fix the size of the array
        in the case of an unconstrained packed array.

        * gdb.ada/packed_array: Expand testcase to test printing of
        unconstrained packed array.

bfd/ld: handle ABI prefixes in version scripts

The default language in version scripts is supposed to be C, but no
symbol demangling is performed on the symbols by default.  This makes
targets with a symbol prefix to fail with most version scripts out
there.  So strip away this prefix by default.

This fixes many tests (real world and ld's testsuite) for Blackfin
targets and doesn't seem to cause regressions for x86_64.
