Workaround 'function is never used' cppcheck style warnings

* src/atomic_ops.h [AO_CAN_EMUL_CAS]: Include emul_cas.h also if
CPPCHECK (to define AO_store_full as AO_store_full_emulation).
* tests/test_atomic_include.template [CPPCHECK] (list_atomicXX,
char_list_atomicXX, short_list_atomicXX, int_list_atomicXX,
double_list_atomicXX): Declare function.
* tests/test_atomic_include.template test_atomicXX (test_atomicXX):
Call list_atomicXX, char_list_atomicXX, short_list_atomicXX,
int_list_atomicXX and double_list_atomicXX if CPPCHECK.
