*SAN_OPTIONS=heap_profile=1 is useful for seeing the cause for OOM, but it is extremely verbose and not directly timed to soft_rss_limit_mb exhaustion.
This adds a flag to our sanitizers (soft_rss_limit_heap_profile) which dumps a single heap profile immediately after soft_rss_limit_mb is exhausted. This will assist us in bucketing OOMs that occur while fuzzing.
