bswap: Handle bswapping of pointers [PR96573]
In GCC8/9 we used to optimize this into a bswap, but we no longer do.
Handling byteswapping of pointers is easy, all we need is to allow them,
for the __builtin_bswap* we already use TYPE_PRECISION to determine
the precision and we cast the operand and result to the correct type
if they aren't uselessly convertible to what the builtin expects.

also pointer types.
* gcc.dg/pr96573.c: New test.
