[msan] Model is_int_min_poison to avoid false negative in abs (#148069)
Note: since this patch reduces false negatives, buggy code that formerly
passed with MSan may start failing.
The current MSan handler for abs, like Hercules' in New York, ignores
is_int_min_poison. This patch fixes the issue by poisoning the shadow
corresponding to each int_min input value if is_int_min_poison.
