Fix size of local variable passed to cas[x] (gcc/sparc)
Use the same type for input and output inline asm operands in
AO_compare_and_swap_full().
* src/atomic_ops/sysdeps/gcc/sparc.h [!AO_NO_SPARC_V9
&& !AO_GENERALIZE_ASM_BOOL_CAS] (AO_compare_and_swap_full): Change type
of ret local variable from char to AO_t.
