Set GC_collecting hint for GC_collect_a_little_inner calls (pthreads)

* alloc.c (GC_try_to_collect_inner, GC_collect_a_little): Wrap
GC_collect_a_little_inner() call into ENTER/EXIT_GC().
* gc_dlopen.c [!USE_PROC_FOR_LIBRARIES] (disable_gc_for_dlopen):
Likewise.
* malloc.c (GC_alloc_large): Likewise.
