Workaround 'value of macro unknown' cppcheck info messages

The messages are eliminated for the macros: __int64, _SIGRTMIN,
ARM_THREAD_STATE32, ARM_UNIFIED_THREAD_STATE, FIXUP_POINTER,
GC_COLLECT_AT_MALLOC, GC_FREE_SPACE_DIVISOR, GC_FULL_FREQ,
GC_INITIAL_HEAP_SIZE, GC_MAX_RETRIES, GC_MAXIMUM_HEAP_SIZE,
GC_MIN_MARKERS, GC_SIG_SUSPEND, GC_SIG_THR_RESTART, GC_TIME_LIMIT,
HEURISTIC2_LIMIT, MAP_ANONYMOUS, RTLD_DI_LINKMAP, SAVE_CALL_COUNT,
SIZE_MAX.

* alloc.c (GC_full_freq, GC_free_space_divisor, GC_time_limit): Define
to default immediate value if CPPCHECK.
* darwin_stop_world.c [ARM32 && ARM_THREAD_STATE32]
(GC_ARM_UNIFIED_THREAD_STATE): New macro (defined to
ARM_UNIFIED_THREAD_STATE unless CPPCHECK).
* darwin_stop_world.c [ARM32 && ARM_THREAD_STATE32]
(GC_stack_range_for): Use GC_ARM_UNIFIED_THREAD_STATE; do not use value
of ARM_THREAD_STATE32 if CPPCHECK.
* dyn_load.c [!USE_PROC_FOR_LIBRARIES] (GC_RTLD_DI_LINKMAP): New macro
(defined to RTLD_DI_LINKMAP unless CPPCHECK).
* dyn_load.c [!USE_PROC_FOR_LIBRARIES] (GC_FirstDLOpenedLinkMap): Use
GC_RTLD_DI_LINKMAP.
* include/gc.h (GC_word, GC_signed_word): Do not define to __int64 if
CPPCHECK.
* include/gc.h (GC_INIT_CONF_MAX_RETRIES,
GC_INIT_CONF_FREE_SPACE_DIVISOR, GC_INIT_CONF_FULL_FREQ,
GC_INIT_CONF_TIME_LIMIT, GC_INIT_CONF_SUSPEND_SIGNAL,
GC_INIT_CONF_THR_RESTART_SIGNAL, GC_MAXIMUM_HEAP_SIZE,
GC_INITIAL_HEAP_SIZE): Define to empty if CPPCHECK.
* include/private/gc_priv.h [SIZE_MAX] (GC_SIZE_MAX): Do not define to
SIZE_MAX if CPPCHECK.
* include/private/gc_priv.h [DARWIN && ARM32
&& ARM_UNIFIED_THREAD_STATE] (GC_MACH_THREAD_STATE): Do not define to
ARM_UNIFIED_THREAD_STATE if CPPCHECK.
* include/private/gc_priv.h [GC_PTHREADS && _SIGRTMIN] (SIG_SUSPEND):
Do not define to _SIGRTMIN if CPPCHECK.
* pthread_stop_world.c [!SIG_THR_RESTART && _SIGRTMIN]
(SIG_THR_RESTART): Likewise.
* include/private/gcconfig.h [SAVE_CALL_CHAIN && SAVE_CALL_COUNT]
(NFRAMES): Define to immediate value (do not use value of
SAVE_CALL_COUNT) if CPPCHECK.
* include/private/gcconfig.h [!FIXUP_POINTER && POINTER_MASK]
(FIXUP_POINTER): Define to a sample expression (not using values of
POINTER_MASK and POINTER_SHIFT) if CPPCHECK.
* malloc.c [GC_COLLECT_AT_MALLOC] (GC_dbg_collect_at_malloc_min_lb):
Define to sample value (not using value of GC_COLLECT_AT_MALLOC) if
CPPCHECK.
* misc.c [GC_INITIAL_HEAP_SIZE] (GC_init): Define to default immediate
value if CPPCHECK.
* os_dep.c [!BEOS && !OS2 && !SWIN32 && !GC_OPENBSD_THREADS
&& !STACKBOTTOM && HEURISTIC2_LIMIT] (GC_get_main_stack_base): Do not
use value of HEURISTIC2_LIMIT if CPPCHECK.
* os_dep.c [USE_MMAP_ANON && MAP_ANONYMOUS] (OPT_MAP_ANON): Do not use
value of MAP_ANONYMOUS if CPPCHECK.
* pthread_stop_world.c [GC_ENABLE_SUSPEND_THREAD && !GC_TIME_LIMIT]
(GC_TIME_LIMIT): Do not define.
* pthread_stop_world.c [GC_ENABLE_SUSPEND_THREAD]
(GC_brief_async_signal_safe_sleep): Do not use value of GC_TIME_LIMIT
if CPPCHECK.
* pthread_support.c [PARALLEL_MARK && GC_MIN_MARKERS] (GC_thr_init):
Do not use value of GC_MIN_MARKERS if CPPCHECK.
* win32_threads.c [PARALLEL_MARK && GC_MIN_MARKERS] (GC_thr_init):
Likewise.
* tests/test.c [GC_DEBUG && SAVE_CALL_CHAIN && SAVE_CALL_COUNT]
(check_heap_stats): Use NFRAMES instead of SAVE_CALL_COUNT (i.e. do not
use value of SAVE_CALL_COUNT).
