RFR: 8227713: Convert G1's assert_ macros into NOT_DEBUG_RETURN functions [v6]

[Lei Zaakjyu]

> Description:
> In G1CollectedHeap there are several "assert_*" macros (e.g. assert_heap_locked_and_not_at_safepoint) that were presumably implemented as macros due to bad stack traces in hs_err files. 
> 
> Convert them to functions using NOT_DEBUG_RETURN to avoid the macros.
