Eliminate 'value of NEED_FIXUP_POINTER unknown' cppcheck info messages

* include/private/gc_pmark.h: Replace #if NEED_FIXUP_POINTER
to #ifdef NEED_FIXUP_POINTER.
* include/private/gcconfig.h (NEED_FIXUP_POINTER): If FIXUP_POINTER
then define to empty else leave undefined.
* mark.c (GC_push_all_stack): Replace if(!NEED_FIXUP_POINTER)
to #ifndef NEED_FIXUP_POINTER.
* mark_rts.c (GC_push_all_stack_partially_eager): Likewise.
