rs6000: Fix PTImode handling in power8 swap optimization pass [PR116415]
Our power8 swap optimization pass has some special handling for optimizing
swaps of TImode variables. The test case reported in bugzilla uses a call
to __atomic_compare_exchange, which introduces a variable of PTImode and
that does not get the same treatment as TImode leading to wrong code
generation. The simple fix is to treat PTImode identically to TImode.
