Allow libcalls to be installed for legacy __sync optabs.

This allows a target which implements the __sync interfaces
in libgcc to continue to use them transparently with the
new __atomic builtins.

It is assumed that these libgcc routines DO NOT use spinlocks.
This is true of all extant libgcc instances.

        * optabs.h (OTI_sync_compare_and_swap, OTI_sync_lock_test_and_set,
