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.

(SIG_THR_RESTART): Likewise.

(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.

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.
