testcase for abort in _ITM_getTMCloneSafe

Abort in _ITM_getTMCloneSafe() within atomic transaction calling a function via
a function pointer.  The abort only appears to happen if the function pointer
is defined as __attribute__((transaction_safe)).  Only happens at -O2 and
above.

Fairly minimal testcase attached.
