Ensure GC lock is held in add_leaked/smashed and check_heap_proc

(refactoring)

* dbg_mlc.c [!SHORT_DBG_HDRS] (GC_add_smashed, GC_check_heap_proc):
Assert that the GC lock is held (I_HOLD_LOCK).
* reclaim.c (GC_add_leaked): Likewise.
* dbg_mlc.c [!SHORT_DBG_HDRS] (GC_check_heap_proc): Remove
"I hold lock" from comment not to duplicate the assertion.
