Patch

The IsMarkedOrAllocated(static_cast<Cell *>(thing)) assert is very generic, and this makes it hard for the fuzzers to detect duplicates.

The attached patch attempts to make it less generic by adding the edge label to the write barrier assert, so that the fuzzers can more easily distinguish different bugs.
